Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:Evolution is a process that results in changes in the genetic material of a population over time. So its true!
Explanation:
This is correct!
Answer:
herbivore eats only plants, ex. cow, squirrel, caterpillar
carnivore eats only meat, ex. tiger, wolf, shark
omnivore eats both plants and meat, ex. humans, birds, dogs
decomposer feeds off and breaks down organic material, ex. mushrooms, fungi

Extinct is correct. When no members of a species remain, the species is said to be extinct.
