Which of these members of the food web brings energy into the ecosystem by transforming energy from the sun into chemical energy
lana66690 [7]

Answer:cacti

Explanation:

In an ecosystem,the ultimate source of energy is the sun. Plants take up this energy from the sun to produce food. Animals eats up plants and when they die ,they decompose. This continuing process leads to the transfer of energy from one trophic level to another in the ecosystem.

Plants ,algae and some bacteria are the primary producers in the ecosystem.they are able to make their own food and support the entire living system. They extract inorganic nutrients and energy from the environment, in order to make their food. Animals(herbivores) eats up the plants and other animals(carnivores) eat up such animals. This situation sets up a chain of flow of energy from the producer to the consumer and back to the environment.
