In the above food web green algae is the producer, periwinkle and microscopic animals are primary consumers; mussel, barnacle, dogwhelk and crab are secondary consumers; dogwhelk and crab comes under tertiary consumer; dogfish is a quaternary consumer.

What is a food web?

It is a natural interconnection of several food chains in a single ecosystem. Each food chain supplies energy and nutrients through the ecosystem. There are four food webs producer, herbivores, carnivores, omnivores and decomposers.

Here green algae comes under autotrophs(prepares their own food), periwinkle and microscopic animals are herbivores(depend on producer); mussel, barnacle, dogwhelk and crab are carnivores(depend on herbivore); dogfish is an omnivore(depends on both producer and carnivore).

Answer:

This is for the table at the top

Plentiful roaming space- increase - because they have more space they can live in.

Severe drought - decrease- because they wont have enough water

abundant food source - increase - Because they have enough food to sustain themselves

Habitat destruction - decrease - Because they won't have a place to live in

Elimination of predators - increase - Because there will be less animals hunting them for food.

Lack of competition - increase - Because they won't have to compete for food which will allow them to have more.

Disease outbreak - decrease - Because the disease will kill a lot of them and can potentially cause birth rates to go down

The reason for the change in the hands of the chimpanzee include:

Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
Mutations in chimpanzee DNA ( Represents a reason for the change)
Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
Sexual reproduction ( Doesn't represents a reason for the change)
Differences in enhancer sequences( Represents a reason for the change).

<h3>What is mutation?</h3>

Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:

When there is spontaneous break down of deoxyribonucleic acid (DNA).
Change in a single nucleotide of the DNA.
when there is additions or deletions of nucleotide in a DNA strand.

A change can be noticed in an animal such as Chimpanzee when the following occurs:

Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.

Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

When Jorge looks at the Moon from Earth, he sees different phases of the Moon depending on the time of the month he observes the

bulgar [2K]

The moon has different phases because it’s around different times. For example, let’s say you go outside and look at the moon at 11pm, then you go and look at it again at 12 pm, it’s going to have a different phase because it’s not at the say time.

In a closed system, the total energy prior to an energy transformation is _______ the total energy after. A. equal to B. unrelat

nikklg [1K]

Hey there mate!

Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.

But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.

So, it really depends whether the system closes up, or whether it would be free of energy.

So, in this case, your correct option to this answer would be (option A).

In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after.

I hope this helps you!
