Why do all living things depend on green plants?

Answer 1

Living organism depend on plants because of the plants capability to do photosynthesis. Photosynthesis is converting the sun energy into a glucose type sugar. Sugar is a type of energy that all living organisms need.

Answer 2

Plants form the bottom of the food web for many organisms, taking energy from the sun, and converting it to usable energy for itself. Animals can take advantage of this energy by eating the plant, thus gaining the energy.

This is why a lot of living organisms depend on plants for food, though not all of them do.

Ie, carnivores.

Though carnivores often eat things that are omnivores or herbivores.

Answer 3

Organisms depend on each other because most of them need each other for food. Lets take frogs for example, frogs depend on other insects to feed them and keep them alive. Humans depend on animals as well, such as meat from animals, and eggs from birds or some reptiles. Insects depend on other insects for food as well. A Praying mantid depend on other insects for food.

Answer 4

In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. This energy can be traced back to green plants so green plants are the source of energy for ecosystems. eg

plants ------ insects -------- birds --------- hawk

Hawks eat small birds, small birds eat insects, insects eat plants.
