In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.
The percentage of energy transferred to the deer after feeding on the grass is 10%.
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.
The correct answer is Option C.

Answer:
-300 N
Explanation:
The key words here are "constant speed". By this, we mean that all the forces on the object (the sailing boat here) are balanced - so they must be equal in magnitude.
Here, we know that the boat has a forward force of 300 N. Because the forces are balanced, then the backward force must also have a force with magnitude 300 N.
However, note that because the backward force is in the opposite direction as the forward force, we must put a negative sign on the 300. So our answer is: -300 N.
Answer:
awnser mine and ill awnser urs
Explanation:
Explanation:
Bb x Bb
1BB, 2Bb, and 1 bb
Let B=black fur allele(dominant) and b=white fur allele(recessive),
¾ of the rabbit will be black while ¼ will be white.
Hence,
¾×100%=75%
¼×100%=25%
The answer is c. echinodermata
