What would happen if the population of the bird species shown in the ecosystem in Figure 4-1 were to suddenly decrease?•The grass population would increase
•The fish population would increase
•The fish would occupy the bird's niche
•The grass and fish would compete for resources
What would happen if the population of the bird species - 1

Answers

Answer 1
Answer:

Answer: The fish population would increase.

This is because if the number of birds decrease the number of  fishes would automatically increase as there would be less birds to eat the fishes.

According to trophic pyramid if the number of species at higher tropic level decreases the number of species at lower trophic level increases

  • Rest all the options has no interconnections like grass has nothing to do with the fishes and birds as well
  • Fishes cannot occupy bird's niches because both the niches are different
  • The grass and fish cannot compete for resources because their resources are different
Answer 2
Answer:

Answer:

The second option which is, "The grass population will increase" is the correct option.

Explanation:

  • In the above picture, a bird is eating a fish from the pond. if the population of birds in a community decrease due to some reasons, then there will be no birds for eating fishes.
  • This will cause an increase in the population of fishes.
  • But there is no connection of grass with the increase and decrease of birds species.
  • In ecological pyramids, Birds (secondary consumers) are high than the fishes (primary consumers).
  • As secondary consumers eat primary consumers.
  • Hence the decrease in secondary consumers will increase the population of primary consumers.

Why is the term unique appropriate to describe unicellular organisms

Answers

Answer:

Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell.

Explanation:

Unicellular organisms are composed of a single cell, unlike multicellular organisms that are made of many cells. This means that they each live and carry out all of their life processes as one single cell.

Final answer:

Unicellular organisms are unique because they are single-celled organisms, able to carry out all necessary life processes within a single cell, unlike multicellular organisms that have distinct cells for various functions.

Explanation:

The term unique is appropriate to describe unicellular organisms because these living entities are single-celled organisms. Unique here means there is a distinctive feature about these organisms, which is, they exist as a single cell, unlike multicellular organisms that are made up of many cells. Examples of unicellular organisms include bacteria, yeast, and some protozoans.

The distinctiveness of unicellular organisms also lies in their ability to carry out all necessary life processes like nutrition, respiration, excretion, growth, reproduction, and response to stimuli within their singular cell. In contrast, multicellular organisms have an organ system where dedicated cells carry out these functions. Therefore, the simplicity and functionality of unicellular organisms make them quite unique.
