Since the death rate is higher than the birth rate we can assume that it will be negative. 5-15 is -10 for their life. immigration is also lower than the emigration. 2-4 is -2. adding -2 and -10 will give us -12, hope this helps.
Answer:
plants, particularly in terrestrial ecosystems, and algae in aquatic ecosystems. If the plants or other producers of an ecosystem were removed, there would be no way for energy to enter the food web, and the ecological community would collapse.
Answer:
Plasmolysis
Explanation:
In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.
The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.
The image 2 plant cell is exposed to a solution which is high concentrated solution.
Due to this high concentrated solution the water present in the cell is send out by exosmosis.
Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.
This shrinkage of protoplasm by loss of water is called plasmolysis.
Perhaps the most significant factor that affects the biogeochemical cycles in the terms of human involvement is global warming, which disrupts natural cycles on various levels.
