Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.
Electrons become excited in the reaction centre of the Photosystem during the first stage of photosynthesis.
Answer:
The correct order of events of protein synthesis would be from the properties of DNA to forming of polypeptide chain. The correct order would then be B, A, E, D, C.
The following are the correct order of events of translating genetic information on a DNA:
transcription: information of a DNA is transcribed into mRNA in the nucleus.
the mRNA is moved from the nucleus to the ribosome.
amino acids attached to tRNAs are also moved to the ribosome.
the message on the mRNA is translated with the tRNA dropping the amino acid corresponding to the codons on the mRNA and individual amino acids are joined by polypeptide bonds.

Explanation:
is the answer is right can you mark me as brainliest?
Answer:
Because there are two rounds of division without duplication in between, the genetic content is cut in half. Each of the 4 daughter cells will only end up with half of the genetic content of the parent cell. Therefore, after meiosis, the daughter cells would have only 12 chromosomes each.
Answer:
Biodiversity
Explanation:
They will of course exhibit the biodiversity of that given habitat because diversity refers to variation in abroad terms and can be applied to any area.
