Which statement is the best possibly explanation for this? Altered ecosystems regain stability through the evolution of new plant species Geographic barriers prevent the migration of animals to island habitats Destroyed environments can recover as a result of the process of ecological succession Destroyed ecosystems always return to their original state 6. One biotic factors that limits the carrying capacity of any habitat is Activity of decomposers The availability of water Level of atmospheric oxygen Amount of soil erosion 7. Two closely related species of birds live in the same tree. Species A feeds on ants and termites, while Species B feeds on caterpillars. The two species coexist successfully because They interbreed They live in different habitats They use different methods of reproduction Each occupies a different niche 8.

Organisms that eat cows obtain less energy from the cows than the cows obtain from the plants they eat because of the cows. Use energy for their own metabolism Pass on most of the energy to their offspring Store all their energy in milk Convert solar energy to food 23.
