Phytoplankton are the aquatic producers that form the bottom of aquatic food webs, but their total biomass at any given time is actually very small. They are able to support the higher trophic levels because they grow and reproduce much more quickly than the other organisms in the food web.
Answer:
<h2>Facilitated diffusion
.</h2>
Explanation:
1. Diffusion: it is the net passive movement of particles from higher concentration to lower concentration. Diffusion continues until the concentration of substances is equal through out.
2. Facilitated diffusion: is the process of passive transport of molecules or ions across a biological membrane and requires (via) a specific carrier protein.
3. Facilitated diffusion is passive type and require specific protein and it requires no energy from the cell.
4. It requires specific proteins through which molecules move from one side to another.
It's the t RNA.. t stands for transfer
Answer:
We (humans) remove nutrients from the land and discharge them into aquatic environments. On one hand, this leads to soil depletion on the land, and on the other hand, an over abundance of the nutrients and pollution of water sources.
Explanation:
Answer:
The carbohydrate is one of the most important nutrients needed in the diet of an athlete, as they are important to increase their performance during physical activity and exercise.
Carbohydrate is the main source of energy needed by the brain and by our body for its proper functioning. when carbohydrates are eaten up they are broken up into small sugar unit called as glucose.
These glucose unit are stored in the muscle and liver in the form of glycogen to be used as a fuel at the time of exercise and during intense physical activity. It is known to enhance the athlete performance by delaying the fatigue and help them to compete for a longer period of time.
