What happens to the ecosystem’s resilienceto disturbance

Answers

Answer 1
The loss of an ecosystem's ability to recover from a disturbance—whether due to natural events such as hurricanes or volcanic eruptions or due to human influences such as overfishing and pollution—endangers the benefits (e.g., food, clean water, and aesthetics) that humans derive from that ecosystem.

What are some land adaptations of vertebrates?

Answers

The vertebrates that first invaded the land possessed a series of pre-adaptations, such as air-breathing and limb-based locomotion, that allowed them to move about effectively on land; however, other behaviors such as reproduction and swallowing likely tied these vertebrates to the water

When moving to land, animals faced several changes to adapt to the new environment, like lung and limbs development, tegumentary cover, and internal fertilization.  

Which are the adaptations of vertebrates to land habits?

Any change to a new environment needs adaptations.

Aquatic animals had to face many changes in their morphology and physiology when changing to terrestrial habits. Some of them are,

Lung development

The most significant change is probably lung development, needed to produce gas interchange between tissues and the air.

Once on the ground, animals need to interchange oxygen and carbon dioxide with air. They managed to do so through the respiration process in which the circulatory and respiratory systems work together.

Tegumentary cover

Animals needed to develop a new thicker and harder tegumentary cover.

It needed to be more resistant, especially to avoid or reduce dehydration.

Also, the tegument provides protection when facing new environmental pressures -predation among them-.

Limbs development

Another significant change was limb development, which was obviously needed to move on the ground.

Locomotion on the ground required a new pattern of bone arrangement and many muscle changes.

The muscular system suffered many modifications because animals needed to move facing gravity pressure.

Internal fertilization

Animals needed to face another change related to their reproductive system.

They could no longer make use of external fertilization, as they used to do in aquatic environments.

They developed reproductive organs needed to insert sperm cells into the female body and fertilize the egg cells inside the females.
