Ecological efficiency is the term used to describe how much energy will be passed from lower food pyramid level into the higher level. The amount of energy in primary level will be much higher than tertiary. The difference of level of tertiary(3) with primary(1) would be two level.
Assuming that the ecological efficiency is 10%, then the <span>primary consumer level would be: 50 kcal * 10^(3-1)= 5000 kcal</span>
Answer:
Biotechnology allows farmers to grow more food on less land using farming practices that are environmentally sustainable. Through biotechnology: Seeds yield more per acre, plants naturally resist specific insect pests and diseases, and farming techniques improve soil conservation.
Explanation:
The properties of gamma which paved its way to the area of medicine are having high energy of all the waves in the spectrum. With this they can penetrate into almost all surfaces. One application would be its use in killing cancer cells and to examine the internals of the body.
Because although one organism is harmed, the other benefits. So the organism that benefits won't stop the action that is harming the other. Hope that makes sense!
A decrease in the paved surfaces on earth will increase amount of light reflected or increase albedo.
<h3 /><h3>What is a paved surface?</h3>
A paved Surface refers to a surface covered by concrete, asphalt, masonry, or a similar material.
Paved surfaces have low albedo, that is they have low light reflectivity.
<h3>What is the effect of paved surface of Earth on albedo?</h3>
Since paved surfaces have low albedo, a decrease in the paved surfaces on earth will increase amount of light reflected (albedo).
