From reasoning and analyzing evidence. Hope this helped :D
I would say tropism because plants can’t respond to their environment by controlling gravity!
Experimentation makes it possible for researchers to isolate cause and effect by allowing the researchers to manipulate one factor while controlling the other factors. This is achieved by creating two groups, subjects are put in these groups randomly in order to reduce experimental biases.
The two groups are the experimental group and the control group. The subjects in the experimental group will be exposed to treatment while the subjects in the control group will not be exposed to the treatment.
Answer:
Food, sunlight, water, oxygen and shelter :3
Explanation:
As a growing population reaches the limits of the available resources in an environment, its size levels off to "match" the amount of resources available. In doing so, the population reaches its carrying capacity.
Another factor that affects the carrying capacity of an ecosystem is the rate at which decomposers can break down the remains of dead organisms within the ecosystem. The faster an ecosystem can recycle the nutrients in dead organic matter, the larger the populations it sustains can become.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.
