How are predation and competition essential for maintaining a thriving ecosystem?

Biology
1 answer:
Elis [28]3 years ago
8 0

Answer:

<u>Both of these are necessary to maintain overpopulation of any species in an ecosystem.</u>

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.

kolezko [41]

Answer:

Starting at the spinal cord, the subdivisions of the brachial plexus are (in order): roots, trunks, divisions, and cords.

Explanation:

The brachial plexus is a nervous network that is located at the base of the neck, and connects the spinal cord to all peripheral nerves in the arm. It is composed of five spinal roots (C5, C6, C7, C8 and T1) that join, forming three primary trunks: the upper trunk, which comes from the anterior branches of nerves C5 and C6, the middle trunk, comes from the anterior branch of nerve C7 and the lower trunk: it comes from the anterior branches of nerves C8 and T1. Once the clavicle is passed, each trunk is divided into an anterior and a posterior division, which will be reorganized to form the secondary trunks, fascicles or cords. The set of the posterior branches forms the posterior cord. The union of the anterior branches of the upper and middle trunk forms the lateral cord and the anterior branch of the lower trunk gives rise to the medial cord.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two
Readme [11.4K]
The correct answer is B. This question relates to using a punnet square to determine the genotypes of the offspring. Two heterozygous parents expressing a polka-dot tale must have genotype Pp each. 

Using a punnet square, this will produce 4 possible genotypes in equal probability:
PP - polka dot
Pp - polka dot
Pp - polka dot
pp - solid tale

Therefore there is a 75% change of getting polka dots in the offspring, and a 25% chance of solid tale.

A. is an incorrect answer because only 50% of offspring will be type Pp, another 25% will be expressing double dominant alleles for P as PP, which will still express polka dots.
