Answer:

1. producers, plants, autotrophs

2.primary consumers, herbivores, 1st order heterotrophs

3.No. Why? Because organisms such as humans are omnivores, meaning they can eat both meat and plants and may act as 1st, 2nd or 3rd level heterotrophs.

4. sunlight

5.Producers (plants) have the most energy in a food chain or web (besides the sun) and they give an organism more energy than a primary consumer or secondary consumer would.

6.Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Answer:

1.producers, plants, autotrophs

2.primary consumers, herbivores, 1st order heterotrophs

3. organism may not always occupy the same trophic level, depending on the food web. Assigning organisms to trophic levels isn't always clear-cut. For instance, humans are omnivores, meaning they can eat both plants and animals.

4.the SUN/SUNLIGHT is the major source of energy for organisms and the ecosystems of which they are a part.

5.Explanation: Producers (plants) have the most energy in a food chain or web (besides the sun) and they give an organism more energy than a primary consumer or secondary consumer would.

6.Answer. Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level
