In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.
Energy pyramid in the ecosystemThe producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.
The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.
Thus, one can effectively conclude that:
Herbivores have more energy available to them than carnivores.There are fewer tertiary consumers than secondary consumers.Soil organisms recycle nutrients but not energy back into the ecosystem.More on the energy pyramid can be found here: https://brainly.com/question/2515928

seafloor spreading is caused by ___ (divergent, convergent, transform) boundaries and results in ___ (more continental land, mountains on land, mid ocean ridges)
Answer:
divergent,mid ocean ridges
Explanation:
the seafloor diverge from each other causing the land to go thinner and thinner and thinner and make an opening between the floors and continue to move away from each other until they touch a more firm land to be able to stop, then the mid ocean ridges come between the floors where inside there is water and on the side there are the ridges

If the membrane was completely permeable,the concentration inside the cell would be about the same as the outside. Give reason?
If the cell membrane is permeable to some solute, this means the solute is free to move in or out of the cell, depending on its concentration gradient. The solute will move by diffusion from the area with high concentration to the area with low concentration. So if the concentration of this solute is higher outside of the cell compared to the inside, then it will move into the cell until its concentration is equal on both sides.

why farmers are manuring at the roots of the plant
Answer:healthy plants
Explanation:the farmers use raw manure on their fields because it is an excellent source of nitrogen (N), phosphorus (P) and potassium (K), which are all nutrients necessary for plants to grow and thrive.
Answer:
The reason why farmers put manure at the roots of the plants is because that is how most of the nutrition is taking up into the plant. Most of the minerals in the earth are absorbed into the plant for usage by the roots which is why the manure would be placed where the roots are. However, it's important to not put too much because that can actually cause the roots to get burned because there is too much minerals so it's important to keep a balance.

many marine organisms depend on upwelling to bring nutrients to surface. how might El Nino affect a fisherman's way of life
The upwelling of seawater refers to the rising up of the deeper and cold water towards the surface of the sea. This cold water is comprised of the valuable and essential nutrients and as they move upward, it provides these nutrients to the marine organisms.
What is El Nino?El Nino is usually defined as the large-scale changes in the climate that occurs due to the interaction between the ocean and the atmosphere. It leads to the episodic rise in the temperature of the sea surface, which typically occurs in the central and the eastern part of the central Equatorial Pacific.
The occurrence of El Nino leads to the reduction of the upwelling of deep-sea cold water. During the time of this harsh climate, the fishes die or they sometimes migrate into some other places where they can obtain their food. Due to this, the fisherman cannot go fishing.
Thus, the occurrence of El Nino directly affects a fisherman's life.
