The prevailing theory at the time was that plants grew by eating soil, and van Helmont devised a clever investigation to test this idea. He weighed a willow tree and weighed dry soil. He planted the tree, watered it and then left it for 5 years. He then re-weighed the tree, which had increased in mass by over 12 stone. He dried the soil and weighed it, showing that the soil was almost the same mass. He concluded that the tree grew by drinking water.

miss Akunina [59]

Answer:

1. interactions

2. environment

3. sun

4. photosynthesis

5. chemical

6. producers

7. food

8. energy

9. organisms

10. herbivores

10. first

12. Heterotrophs

13. second

Explanation:

An ecosystem consists of a community of living organisms interacting  with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.

Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
