Answer:
Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:
- Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
- Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.
Answer:
The purpose of ethical guidelines for handling of experimental subjects is to ensure the safety and well-being of all living creatures in an experiment. Ethical guidelines include issues such as human rights, animal welfare, safety compliance with the law, conflicts of interest, health standards.
Answer:
3. The equator receives more direct sunlight than the North Pole.
Explanation:
<h2>The equator is the longest latitude at 0°.</h2><h2>The equator isn't influenced any change when the earth revolves around the sun cause winter and summer. </h2><h2>That's why equator is warmer than north and south pole.</h2>
<h2>I hope you understood</h2>
If there were less greenhouse gases, much of the infrared radiation that is converted to heat today would not be trapped in the earth's atmosphere. The earth's temperature would cool, and a new Ice Age would occur. Many plants and animals could not survive in this new condition, oceans would freeze, and weather patterns would change.
Hope that helped
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
