These cells are called plasmodesmata. They are significant in the symplastic flow (meaning through the cytoplasm) of water and other molecules in the plant. A membrane called desmotubule runs along the pores of adjacent plasmodesmata. These cells are also significant in the communication between cells.
Secondary consumers eat primary consumers, which eat producers. If the population of secondary consumers should increase, the population of primary consumers will decrease, and that means less producers are eaten, thus there will be more producers.
The idea that some living
