Why are plants an important foundation for many ecosystems?

Answer 1

Well plants and trees create living habitats for animals. they also absorb carbon dioxide and produce oxygen for humans and animals to breath. they also provide shelter and food to some animals as well. Like koala's and birds

Answer 2

Biochemically speaking:

Plants can photosynthesise, which is the process of storing the energy in sun light as carbohydrate molecules. The light's energy is used to convert simpler molecules (carbon dioxide and water) into more complex, energy rich carbohydrates.

Although some bacteria and algae can photosynthesise, most land animals will rely solely on plants to feed a food chain/web (or ecosystem). Therefore, without plants, there would be too little accessible energy to support the ecosystem.

Plants are also the source of most nitrogen for land ecosystems. The organic nitrogen compounds originally comes from bacteria, but is exchanged for carbohydrates in a symbiotic relationship between the bacteria and the plant. Without the plants, most ecosystems on land would have a distinct shortage of nitrogen with which to build macromolecules.

In marine environments, many marine organisms will also rely on plants as a food source, despite the presence of photosynthesising bacteria.

Biologically speaking:

Plants can provide shelter, camouflage and safety (high up a tree). All of these are important for survival.

Answer 3

Plants play a crucial role in ecosystems by producing oxygen, providing food and habitat for many animals, stabilizing soil, and regulating the climate by absorbing carbon dioxide. They are also at the base of the food chain, serving as a primary energy source for other organisms. Without plants, many ecosystems would collapse due to the lack of essential resources and services they provide.

Answer 4

They are necessary because the plants feed other animals that get eaten by other animals that are eaten by others
