Activity 5: What Do You Think?

• Plants compete among themselves for moisture, inorganic nutrients, space, light, and air. Resources in any ecosystem are limited.
• Plants compete through the efficiency through which they uptake and use water and by their root distribution, both vertical and horizontal.

Student Conceptions
Students will be familiar with competition among organisms in the form of predation in animals. The What Do You Think? questions ask the students to consider competition among plants. Also, stress that competition can occur among microorganisms as well.
