Which of the following would cause an increase in competition in a forest ecosystem?
increase in the number of plants
decrease in the number of plants
decrease in the number of bears
increase in the amount of sunlight

increase in the number of plants

Explanation:

Increasing plant numbers may cause competition between plants for sunlight, water and soil nutrients. As we know these resources are limited, plants don't have them all the time, so when a plant population increases, they tend to compete for resources.

Plant competition is an important process in both natural communities and agricultural environments. In agricultural systems, such competition can be seen by increasing the number of plants through weeds. The vegetative impact of weeds on agroecosystems is considered competition if there is a reduction in the amount of resources available for the crop and, in this context, root development influences plant competitiveness and survival.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.
