An autotroph is an organism that produces its own food from simple substances available in its environment. Autotrophs usually use inorganic chemical reactions or light energy in producing their food and are usually the producers in a food chain. Examples of autotrophs are plants and algae.
Commensalism is a type of relationship between organisms of two species where one organism benefits from the relationship and the other organism is not affected by it (neither benefits nor harmed).
Answer:
a) stomata
Explanation:
The stomata are little pores / doorways / openings that have the express purpose of allowing gases in and out. Without this, plants would not be able to fix carbon, which is essential in respiration.
Why not c or b: The xylem and phloem channel water through the plant, not gases.
Why not d: The cuticle is the waxy outer layer of the leaf meant to protect it, not allow gases through.
