Answer:

Both of these are necessary to maintain overpopulation of any species in an ecosystem.

Explanation:

Predation is an act in which one organism eats another organism present in the ecosystem.

The one eaten is called prey, while the dominant organism is called Predator.

Since an ecosystem is made up of many organisms along with the natural resources present in it.

This gives rise to different species competing against one another.

If one of these species is at a certain advantage, their population will rise uncontrollably hence to prevent this a predator plays a major role.

On the other hand, competition is a term which describes the harm caused to two different organisms.

This is due to the limited number of natural resources like food, water or shelter etc.

Organisms who are less likely to adapt according to the changing environment ultimately die.

For example, Plant roots over time lessen the amount of nitrogen present in the soil, causing the neighboring plant to die.

Question 23 (6 points)

Stels [109]

Answer: 1. Sea urchins and sea otters

2. They are prey for carnivores.

3. Sea otters, star fish

Explanation:

Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.

Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins. So, starfish and kelp forests are the prey in the marine ecosystem.

Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.

Sertoli cells are stimulated by ________, while leydig cells are stimulated by ________.

Lena [83]

Sertoli cells are stimulated by FSH, while leydig cells are stimulated by LH.

<h3>Sertoli and Leydig Cells:</h3>

The creation of T is stimulated by LH in Leydig cells, while the production of regulatory molecules and the nutrients required for maintaining spermatogenesis are stimulated by FSH in Sertoli cells in concert with T. As a result, Sertoli cells indirectly control spermatogenesis via T and FSH.

The growth and maintenance of the male reproductive system and spermatogenesis depend on LH-stimulated Leydig cell androgen synthesis. The interstitial cells of Leydig, which are concentrated heavily in the testis of newborn boys and adult males following puberty, release testosterone. Interstitial cells are another name for Leydig cells. The interstitial spaces outside of seminiferous tubules are where they can be found.

16. In which of the following situations are the phenotypes of F2 offspring expected to follow

scoundrel [369]

Answer:

Explanation:

The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.

There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.

A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.

Hence, the correct option is C.
