10% of available energy flows from one trophic level to the next. What happens to the other 90%?

1 answer:

5 0

Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers. An example would be birds that eat bugs that eat leaves. Secondary consumers are eaten by tertiary consumers. Cats that eat birds that eat bugs that eat leaves, for instance.

Answer:

E) Elephants help other populations survive by repelling many large African predators

Explanation:

Elephants are large mammals. Elephants in Africa have a height of 4 meters and weigh up to 7 tons.

The role of elephants in the ecosystem is very important especially its impact both directly and indirectly on the environment. With a large size and height, other predatory animals such as lions, tigers, coyotes, hyenas do not want to get close to elephants. Elephants are animals that prefer to group. While still breastfeeding will be very protected by the mother for up to 3 years. Elephants have an average age of up to 70 years. Perhaps very few elephants have fallen prey to predators. Thus elephants are animals that indirectly protect other animals in Africa. Things like this also indirectly make grasslands become more fertile and other animal species also become more numerous.

So the most appropriate answer is E. E) Elephants help other populations survive by repelling many large African predators

In Drosophila, straight wings are dominant to curved wings (c), smooth eyes are dominant to sparkling eyes (spa), and tan body i

77julia77 [94]

Answer:

$\frac{1}{8}$

Explanation:

Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be $\frac{8}{64}$

= $\frac{1}{8}$
