Question

Describe a minimum of two ways that plants changed the land environment to support the emergence of land animals.

a) Plants stabilized soil, preventing erosion, and provided shelter and food sources for animals.
b) Plants reduced atmospheric carbon dioxide and released oxygen, benefiting animal respiration.
c) Plants increased soil nitrogen levels and supported microbial diversity, aiding animal digestion.
d) Plants facilitated the creation of water bodies, allowing aquatic habitats for land animals.

Answer 1

Plants have changed the land environment to support the emergence of land animals through soil stabilization and providing food and shelter. They have also benefited animal respiration by reducing atmospheric carbon dioxide and releasing oxygen. Furthermore, plants have supported animal digestion by increasing soil nitrogen levels and promoting microbial diversity.

Step-by-step explanation:

Plants have changed the land environment in several ways to support the emergence of land animals. Firstly, plants have stabilized soil, preventing erosion and providing shelter and food sources for animals. Secondly, plants have reduced atmospheric carbon dioxide and released oxygen, which benefits animal respiration. Additionally, plants have increased soil nitrogen levels and supported microbial diversity, aiding animal digestion.
