Amanda [17]

Answer;

-Pellicle

Explanation;

-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.

-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.

Why are fossil fuels considered a nonrenewable energy source?
joja [24]

Fossil fuels are considered a nonrenewable energy source because once fossil fuels are used, they are gone. So, the correct option is A.

<h3>What do you mean by Nonrenewable energy?</h3>

Nonrenewable energy may be defined as that energy that once consumed can not be replenished for millions of years.

Fossil fuels are examples of nonrenewable energy resources. The formation of fossil fuels may take over millions of years. This fuel is made naturally by the decomposition of dead and decayed organic living matter.

Therefore, the correct option for this question is A.

1) A plant gets 628.3 kcal of energy from the sun, what energy is left at the quartenary consumer level?
Jobisdone [24]

1. The energy left in the Quaternary consumer level is 0.06283 kcal.

2. 0.65 units of energy  is still available at the tertiary consumer level.

<u>Explanation:</u>

Energy flow in an ecosystem obeys the ten percentage law According to which ten percentage of energy from a trophic level gets transferred to the next trophic level. In the given question plants belong to the trophic level , producers  and it transfers 10 percentage of its energy to the primary consumer level.

In the question 1 the energy that the producers have is 628.3 kcal. Ten percentage of this i.e 62.83 kcal gets transferred to the primary consumer level. Ten percent of that which is 6.283 kcal gets transferred to the secondary consumer level.  Ten percent of 6.283 kcal i.e  0.6283 kcal energy is transferred to the tertiary consumer level.

Thus the Quaternary consumer level gets ten percentage of 0.6283 kcal i.e 0.06283 kcal. In question B the initial energy at the primary level is 650 units. Ten percentage of 650 i.e 65 units reach the primary consumer  level. Ten percentage of this 65 units then reaches the secondary consumer level. Thus the secondary consumer level has ten percent of 65 i.e 6.5 units of energy.  

So the energy that reaches the tertiary consumer level is ten percentage of 6.5 i.e 0.65 units.
