2. a(n) □ is an organism that must consume other organisms for nutrients.
3. a diagram that shows the trophic levels of organisms in a food web is called a(n) energy □.
4. a(n) □ shows the sequence of food energy transfer from one organism to another within an ecological community.
5. an organism’s position on a food chain is known as its □ level.
6. a depiction of all the interrelated food chains that exist within an ecological community is called a(n) □.

Explanation:

Question 1

An autotroph that captures energy from sunlight or chemicals to produce food from inorganic compounds is a producer. Producers (like plants, algae, some bacteria) make their own food via photosynthesis or chemosynthesis, using inorganic materials.

An organism that must consume other organisms for nutrients is a consumer. Consumers (herbivores, carnivores, omnivores) can’t make their own food and rely on other organisms (producers or other consumers) for energy and nutrients.

A diagram showing trophic levels of organisms in a food web as an energy pyramid (or trophic pyramid) illustrates energy flow, with producers at the base and top predators at the top, showing energy loss at each level.

Answer:

Producer
