Producers are the most numerous group in an ecosystem. Why?
Producers produce food energy for themselves and all the other levels. ⬜

Soil and temperature conditions in an ecosystem always favor producers. ⬜

As energy flows through the ecosystem, some energy is added at each step. ⬜

There is more room for small organisms than there is for large ones. ⬜

The primary producer uses some of that energy. Because we lose energy each time we move up a trophic level, we have more producers than consumers, more herbivores than carnivores, more primary consumers than secondary consumers. See this Socratic answer for more detail.

Explanation:

Producers produce food energy for themselves and all the other levels

Explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
