Question

predator - prey interactions are an example of *
negative feedback loop.
all of the answers are true
postive feedback loops.
can amplify change in an ecosystem.

all of the following are true about photosynthesis except *
plants absorb yellow and green light during photosynthesis.
carbon dioxide and water is needed to make glucose.
oxygen is produced as a waste product.
glucose is made to store chemical energy.

Explanation:

1. In predator - prey interactions, as predator numbers increase, prey numbers decrease, which in turn limits predator population growth as food becomes scarce. This is a negative feedback loop. Positive feedback loops amplify change, and predator - prey interactions do not typically act as positive feedback loops in the same way.
2. In photosynthesis, plants reflect yellow and green light, not absorb them mainly. They absorb red and blue light. Carbon dioxide and water are used to make glucose, oxygen is a waste product, and glucose stores chemical energy.

Answer:

1. negative feedback loop
2. Plants absorb yellow and green light during photosynthesis.
