The flow of energy from one level to another does not happen with 100% efficiency. The producers only transfer 10% of the energy they absorb from the Sun. The major chunk of the absorbed energy goes into the growth of the producers, the rest gets lost in the form of waste (shedding of leaves, reproduction, etc.) and the remaining 10% is the amount that is available to the primary consumers. So by this logic, if there is 150,000 KJ of energy available at the producer level, then, only 15,000 KJ of energy will get transferred to the primary consumers.
Answer:
The options are
A) they may affect several populations in an ecosystem
B) they cannot be caused by human activity
C) they affect food chains but not food webs
D) They have no effect on living organisms in an ecosystem him
The answer is A) they may affect several populations in an ecosystem
Explanation:
Environmental changes include deforestation and climate changes. Organisms depend on their habitat and climatic conditions for their survival because it determines their food availability too.
When environmental change occurs they may affect several populations in an ecosystem.
Answer:
IgE
Explanation:
Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.
They are known to be produced by produced by plasma cells (white blood cells).
Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.
In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
Hey You!
I believe the correct answer to your question is: Endangered Species. (Also called threatened species).
I Really Hope This Helped You, Good Luck With Your Studies! =)
