According to Darwin's theory of evolution, what causes a struggle for survival in
populations?

Answers

Answer 1

Answer:

In a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).

Answers

Answer:

Decreased production of energy.

Explanation:

Decrease in bile juices may lead to decreased production of energy from eating of food having fats because our body has no ability to absorb fat-soluble vitamins and fatty acids. Bile juices is responsible for the absorption of fat-soluble vitamins and fatty acids which is then transported to the cell for producing energy that is required by our body for different processes. Fats have more energy than carbohydrates and protein so if there is no bile juices are present so it break down does not occurs.

Why are humans dependent on healthy ecosystems throughout the world?

Answers

Answer: Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.

Explanation:

Humans are dependent on healthy ecosystems as they provide resources, regulate climate, purify water, control diseases, offer recreational and cultural values, and drive economic activities.

For a number of reasons, functioning ecosystems are essential to human existence. supplying resources Healthy ecosystems offer vital resources like food, fresh water, clean air, and building supplies like fibre and wood. These materials provide for our basic necessities and are essential to our survival. Genetic and biological diversity: Numerous plant and animal species are supported by ecosystems, which increase biodiversity. Ecosystem stability is ensured by biodiversity, which also increases resilience to environmental changes and offers genetic diversity. The creation of novel foods, medicines, and other useful goods depends on this diversity.

The populations of which organisms will most likely increase as a result of a disease that suddenly reduced the population of Texas horned lizards?

F Grasses and ants

G. Ants and grasshoppers

H Grasshoppers and Texas cottonmouths

J. Texas cottonmouths and red-shouldered hawks​

Answers

Answer:

G

Explanation:

It just is

Texas horned lizards primarily feed on ants, so if their population is suddenly reduced due to disease, the populations of their prey (ants) will likely increase.

What will they lead to if the population growth declines  ?

This, in turn, can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.

Texas horned lizards are known to feed primarily on ants, and as predators, they play an important role in regulating the populations of their prey. When the population of Texas horned lizards is reduced, the ant population can increase, as there are fewer predators consuming them. This increase in ant population can lead to an increase in the populations of other organisms that depend on ants for food, such as grasshoppers.

Grasshoppers are herbivores that feed on vegetation, but they also feed on ants and other small insects. When the population of ants increases due to the reduction in Texas horned lizard population, the population of grasshoppers may also increase as they have more food resources available.

In contrast, Texas cottonmouths and red-shouldered hawks do not directly depend on Texas horned lizards as a food source, so their populations are unlikely to be significantly affected by a reduction in the population of Texas horned lizards.

Therefore, the populations of grasshoppers and ants (option G) are most likely to increase as a result of a disease that suddenly reduces the population of Texas horned lizards.
