Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.
Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.
The most consistent way to obtain information about the evolution of species is to look at the fossil record. Another is to observe the differences between species currently on earth. Another is to use carbon dating.

Answer:
The leukocytes are the main defenses of our body.
Explanation:
From the mother cell it will be a differentiation, from the mother cell to be a mother cell hematopoietic, this will turn into a lymphatic mother cell until it will be 3 different kinds of lymphocytes, the B, T and NK.
Lymphocyte B is the responsible for the inmune system based in antibodies and antigens, due to specific proteins.
Lymphocytes T, are the ones that come from the mother cell of the bone marrow. They are the responsible for the immunity against some illness like cancer.
Lymphocytes NK (natural killer) are the responsible for killing bad cells (like cancer cells) because they "eat" them in a phagocytosis process.
Pollination is a reproduction process foundi in plants where the pollen of one flower is transferred to another flower.
In a more detailed explanation, pollination is a process in which pollinators are protagonists. These (normally insects) go from flower to flower collecting nectar, and during that collection, pollen sticks on to them, and then falls in another flowers interior.
What is pollen?
Pollen are fine particles, of something you might call "dust", produced by the male organs in a plants flower.
