Answer:
"How might different types of organisms--producers, consumers, decomposers--be important to a healthy ecosystem?" (Producers change energy into matter with chemical energy that other organisms can use and then consumers pass the matter and energy on to other organisms by eating and being eaten; decomposers recycle some ...
Explanation:
Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheologically, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. But chemically, which is the more popular of the two, it can be divided into the crust, the mantle (which can be subdivided into the upper and lower mantle), and the core – which can also be subdivided into the outer core, and inner core
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers. B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash. C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population. D) The hawks has to have the smallest population.
