Why are there usually few organisms at the top of an energy pyramid?

Biology
1 answer:
anzhelika [568]3 years ago
4 0

Answer:

Explanation:

The number of organisms near the top of the energy pyramid is usually small, because most of the energy produced is lost due to factors such as exercise and heat. This energy loss occurs multiple times when passing through the pyramid, forcing consumers near the top to require more food. This creates a pyramid with the third consumer at the top and the producer at the bottom.

What statements are true about the biological macromolecules.
photoshop1234 [79]

All biomolecules could be called carbon-based molecules.

The monomers of DNA are nucleotides.

Cell membranes are made, in part, from phospholipids.

The monomers of of starch are monosaccharides.

Explanation:

Biological macromolecules are giant carbon-based molecules. They are polymers made by complex condensation reactions linking them together.

These molecules are typically produced exclusively by living organisms and this is why they are called biological macromolecules.

They are usually classified as organic compounds for their linkage to living processes.

  • It is correct that all biomolecules are carbon-based molecules. They are primarily made up of carbon, hydrogen and oxygen with some other elements.
  • Deoxyribo-nuclei Acids are macromolecules that contains all information about the life of an organism. The DNA is located in the nucleus of cells and it is the genetic matter that controls life activities. The basic unit of DNA is the nucleotides.
  • Cell membranes are structural component of cells that helps to regulate the movement of materials in and out of the cell. They are made up of phospholipids.
  • Monomers of starch are monosaccharides. These are the simplest unit of  starch that cannot be further hydrolyzed. They are usually called simple sugars. Examples are glucose and fructose.

What are statoliths, and what role do they play in plant growth?
erma4kov [3.2K]

Answer:

They are a membrane bound clusters or set of starch grains just like amyloplasts in plant cells. They acts like a gravity sensors. Starch statoliths are the main components which are found in root tips at cells. They are very much close to the vascular bundles in shoots. Statoliths pressurize on the membrane systems which are located inside the cell eg endoplasmic reticulum which results in differential growth.

In gymnosperms and angiosperms, seeds disperse the ________ stage of the life cycle and in mosses and ferns, spores disperse the
Scrat [10]

Answer:

The correct answer is - sporophyte and gametophyte.

Explanation:

In seed producing plants such as gymnosperm and angiosperms the sporphytic part of life cycle is more dominant than the gametophytic part of life cycle. Sporophyte life cycle arise just after the formation of the zygote formation from fertilization of the gametes. The seeds are sporophytic structure that are dispersed to grow and be a full sporophytic plant with root, stem and leaves.

In mosses and ferns the case is different as there are no seed forming present the spores that are gametophytic as has n number of chromosome disperse to produce gametophytic plants that are comparatively small to sporophytic ones.

Thus, the correct answer is - sporophyte and gametophyte.
