Explanation:

First Paragraph (Ecosystem/Food Chain Vocabulary)

1. Blank 1: A food chain starts with a producer. So the term is "food chain".
2. Blank 2: Producers (like plants) make food via photosynthesis. So the term is "photosynthesis".
3. Blank 3: First - order consumers (herbivores) eat producers. So the term is "first - order consumers".
4. Blank 4: Second - order consumers eat first - order consumers. So the term is "second - order consumers".
5. Blank 5: Third - order consumers eat second - order consumers. So the term is "third - order consumers".
6. Blank 6: In a food chain, there are a large number of producers (as they are the base). So the term is "large".
7. Blank 7: There are a small number of top - level (last - order) consumers. So the term is "small".
8. Blank 8: Food chains are linked together to form food webs. So the term is "food webs".
9. Blank 9: Decomposers feed on dead animals and break them down. So the term is "decomposers".

Second Paragraph (Energy in Ecosystems)

1. Blank 10: Plants use energy from the Sun to make food. So the term is "energy".
2. Blank 11: Plants convert light energy into chemical energy (stored in food). So the term is "chemical energy".
3. Blank 12: Organisms that eat other organisms (and can't make their own food) are consumers. So the term is "consumers".
4. Blank 13: Energy moves through the food chain as organisms eat each other. So the term is "food chain".
5. Blank 14: The amount of energy available decreases as you move up the food chain (due to energy loss at each trophic level). So the term is "decreases".
6. Blank 15: The Sun continuously provides energy to the ecosystem. So the term is "Sun".
