Answer:

Mutualism

Explanation:

Organisms in an ecosystem interact with one another from time to time. The close interaction between two organisms is referred to as SYMBIOSIS. Symbiosis is of different types depending on the how it affects the involved organisms. The example in this question depicts MUTUALISM.

Mutualism is the type of symbiotic relationship between two organisms in which both organisms benefit from the relationship. This is the case of the LICHEN, which involves the Algae and Fungi.

ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

Primary consumers depend on energy from plants for survival. Higher consumers depend on energy from primary consumers for surviv
yaroslaw [1]
The answer is C
The more plants there are, the more consumers there are. If there aren't enough plants, the consumers have no way of getting energy, and therefore cannot survive. The species also matters, because certain species of plants can only be eaten by certain species of consumers.
