Answer:
Long tail and narrow head.
Explanation:
A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.
Answer:
A)Biomass is transferred from one organism to another when one organism consumes another organism. When a predator organism eats the prey organism, the molecules on the food are broken down by the digestive system into smaller molecules. These smaller molecules like lipids, amino acids, glucose are used by the organism for various purposes.
B) Energy that is not transferred from one organism to another is either used up by the organism for various purposes. Most of the energy is lost into the environment in the form of heat.
c) There are typically fewer organisms at the top of the trophic levels because energy keeps on declining at each trophic levels so the number of consumers which it can satisfy also decreases.
d) Only 10% of the energy passes from one trophic level to another. The rest is usually lost in the form of heat. For example, if there was 100% energy in the producers, only 10% would pass to the primary consumers. The secondary consumers will receive 1%.
