Answer:
In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.
Some of the abiotic factors which affect the distribution of the aquatic life are:
- <em>Amount of light: </em>The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.
- <em>Water flow rate: </em>Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.
- <em>Temperature: </em>Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.
Some of the biotic factors which affect the distribution of the aquatic life are:
- <em>Predators: </em>If there are more number of predators than the preys, then the prey diversity will have a serious threat.
- <em>Aquatic plants: </em>There will be more aquatic biodiversity in the areas where there will be more aquatic plants.
1.To summarize, potential energy is theenergy that is stored in an object due to its position relative to some zeroposition. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. 2. GPE=mgh
Answer:
3.9 billion years
Explanation:
The half-life of potassium-40 is the time it takes for half of it to decay.
After one half-life, half of the original amount will remain.
After a second half-life, half of that amount will remain, and so on.
We can construct a table as follows:

We see that the mass will drop to 10 g after three half-lives.
1 half-life = 1.3 billion years
3 half-lives = 3.9 billion years
Answer:
B because aveoli are part of the lung Branch and capillaries take in the oxygen with blood?
Explanation: my guess since carbon dioxide also needs to be excreted out of lungs.
