18. Research Questions
Draw a diagram of an ecosystem near where you live . Label the factors “biotic” or “abiotic.”
Give two examples of how plants and animals affect their environment
Describe how temperature, light, and soil affect an ecosystem
Think of a forest ecosystem. Now imagine that a large amounts of dust and ash into the air, blocking out sunlight. How might the forest ecosystem be affected if the sunlight is blocked out for a day? For a year? (ANSWER MUST BE A PARAGRAPH)
