Determine the stability of each ecosystem. an ecosystem with populations that mate with unrelated species an ecosystem that has very few species at every trophic level an ecosystem with populations that mate with only related species an ecosystem that has many species at every trophic level (less stable) (more stable)

For the first statement: An ecosystem with  populations that mate  with unrelated species.

The ecosystem will more stable. The mating with unrelated specie will create the ability to cop with any disaster and the chances of extinction of any specie will become very less.

For the second statement: an ecosystem that has  very few species at every  trophic level.

Less stable.

An ecosystem which has a very low number of species ins not so stable because of less biodiversity. Biodiversity is directly proportional to the stability of the specie.

For the third statement: An ecosystem with populations  that mate with only related  species.

Less stable.

The specie which does not have the ability to mate with unrelated specie makes an unstable ecosystem. Because if any thing happens to the ecosystem like climate change, that specie will unable to evolve and go extinct immediately.

For the fourth statement: An ecosystem that has many  species at every trophic level .

More stable:

The ecosystem having a large number of biodiversity at each trophic level leads to a stable an ecosystem. Because biodiversity is directly proportional to the stability of the specie.

   For the first statement: An ecosystem with  populations that mate  with unrelated species.

The ecosystem will more stable. The mating with unrelated specie will create the ability to cop with any disaster and the chances of extinction of any specie will become very less.

   For the second statement: an ecosystem that has  very few species at every  trophic level.

Less stable.

An ecosystem which has a very low number of species ins not so stable because of less biodiversity. Biodiversity is directly proportional to the stability of the specie.

   For the third statement: An ecosystem with populations  that mate with only related  species.

Less stable.

   For the fourth statement: An ecosystem that has many  species at every trophic level .

More stable:

The ecosystem having a large number of biodiversity at each trophic level leads to a stable an ecosystem. Because biodiversity is directly proportional to the stability of the specie.

The right option is "C."

Explanation:

The thesis statement was succinctly placed at the first paragraph for better introduction. The position makes it easier for the reader to regognise at a glance and speedily digest.

..."sailors at sea had no way of calculating the longitude of their ships with any accuracy. As a result, countless sailors died when they lost track of their position and their ships ran aground."

This statement is true !

Explanation: For example in Parasitism, one organism lives inside or on another organism and harms the organism it is living on. The organism that is living inside or on the other organism is relying on the organism that’s getting harmed while it is living on it for its survival by living on it.

5. A.

Explanation:

In these paragraphs, the authors present their ideas through the use of detailed descriptions and vivid details. Moreover, the employ language that attracts the attention of the reader and makes the text engaging. However, the most important element of these paragraphs is the fact that all of them clearly state a thesis, which makes the texts clear and easy to follow, as well as more persuasive.

A-Grass

Explanation:

grass receives its energy from the sun in a process called photosynthesis, the chromophil in the plant foliage transforms sunlight into glucose and this chemical is converted into energy after several processes.

B. Every population in an ecosystem is linked with other populations

Explanation:

An ecosystem is a biological term which refers to all the biotic and abiotic factors present in a particular area which interacts with each other directly or indirectly and affect each other.

In the given case, the interactions and the direct or indirect dependency of the population to each other have been shown as the Aspen trees population which are destroyed by the illness leads to the increase in the population of deer mice. The increase in the population of deer mice can lead to the destruction of the human population as they carry a disease for humans.

Since one population is linked to others directly or indirectly, therefore, the selected option is correct.

Dogs shown in this picture belongs to the secondary consumer trophic level which consumes primary consumer herbivores. These primary consumer herbivores are dependent on grass for food which is a primary producer. If all dogs die, the population of primary consumer herbivores will increase. This increase will lead to decrease in grass at a drastic rate. Therefore, primary producers (grass) will be affected.

Every organism in an ecosystem relies on other species for survival:  species diversity

Reduced options for mates can lead to inbreeding:  genetic diversity

Decreased diversity can lead to increased susceptibility to disease:  genetic diversity

The loss of a producer could result in the loss of consumers:  species diversity

When a population becomes small, diversity is lost:  genetic diversity

Explanation:

That statement is true

Explanation:

Every organism relies on others for survival, even if its abiotic, or not alive.
