1. A group of living organisms of the same species is called a adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. The sum total of all the populations living in an ecosystem is called the adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. The place where an organism lives is called its adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. The term adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety refers to the balanced interaction between the members of a community and their habitat.

2. Green plants are described as adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety because they convert light energy to chemical energy during photosynthesis. This plant food is eaten by herbivorous animals (adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety consumers) who may in turn be the adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety of predatory carnivorous animals (secondary adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety).

3. Organisms that obtain their energy by breaking down dead remains or waste materials are called adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety.

4. During the feeding relationships that occur in an ecosystem, energy flows from organism to organism through food adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety and webs but much of this energy is adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety along the way.

5. Amongst the organisms in a food chain the producers are the most numerous. The numbers decrease at each link and the final consumers are the least numerous. This is represented as a pyramid of adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety.

6. In a food web the producers have the greatest biomass. This decreases at each link and the final consumers have the smallest adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. This relationship can be represented as a adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety of biomass.

7. In a food chain, some of the energy passed on at each link is incorporated in the tissues of the next generation. Most energy is transferred in this way from producer to primary consumer and least energy is transferred at the other end of the food chain. his is represented as a pyramid of adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety.

8. A species is a group of interbreeding organisms whose offspring are adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. The total variation within and between the members of all the species of living things on Earth is called adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety. The distribution of species is influenced by the adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety to niche and habitat they possess.

9. A adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety ecosystem is found to contain a wide variety of species (producers, consumers and decomposers) living and interacting in a balanced way and dependent on one another.

10. Unselective grazers maintain the adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety of plant species present in a grassland ecosystem. adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety reduces the variety of species present in an affected ecosystem.

11. Some human activities such as deforestation cause habitat adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety which leads to a loss of biodiversity.

When a food web is adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety by the removal of one of its members, this may lead to changes in numbers of the remaining members.

13. Animals show adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety adaptations by responding to adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety stimuli in certain ways. These are of adaptive significance since they increase the animal's chance of adaptationsbehaviouralbiodiversitybiomasschainscommunitycompeteconsumersdecomposersdestructiondisruptedecosystemenergyenvironmentalfertilehabitatlostnumbersnutrientsPollutionpopulationpreyprimaryproducerspyramidrequirementsshelterstablesurvivalvariety.
