Based on the jungle food web, which following statement is true?

Terrestrial plant matter has the most amount of energy because they are producers receiving energy from sunlight.

Aquatic plants have the least amount of energy because they are in the first trophic level.

Jaguars receive the most amount of energy because they are top/apex predators who consume few organisms.

Harpy eagles are apex predators which receive most of the energy at the 4th trophic level.

Grass and grain populations would increase because less organisms are consuming them.

Grass and grain populations would remain constant because they are producers.

Owl and bird populations would increase because they have variety in their diets.

Owl and bird populations would decrease because they their food sources are reduced (less).
