Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
Yes, because if you're close to the sea then you will be in a warmer climate. and Ocean currents affect climate in a way similar to winds. Ocean currents move water around the ocean. Warm water currents are currents that move water away from the equator, and cold water currents are currents that move water away from the poles.
Places that are near warm water currents will have a warmer climate.Places that are near cold water currents will have a colder climate.
I think it's b. Or c. Sorry if it's wrong but I'm pretty sure it's one of those
