A taxonomic group of closely related genera is known as?

biology ecology species, communities and ecosystems kingdom fungi monera, protista, fungi

  1. Species

  2. Order

  3. Family

  4. Class

Show answer
Correct Option: A
Explanation:
Species represents a distinct group of the population that really or most likely breed from close animals. This taxonomic class is segregated from other classes through the method of reproduction. It bears minimal taxonomic traits.
It includes individuals that inherit basic similarities.It can be differentiated from other closely connected species because of idiosyncratic morphological characteristics. Option A is the answer

Which of the following is the largest reservoir of carbon?

biology ecology carbon cycling mineral coal carbon cycle

  1. Soil

  2. Atmosphere

  3. Ocean

  4. Sedimentary rocks

Show answer
Correct Option: C
Explanation:

In the ocean, there are underwater sediments and sediment rocks of carbonate like in the form of limestone, dolomite etc. Thus, the correct answer is option C.

How does photosynthesis help to maintain the percentage of oxygen and carbon dioxide in the atmosphere?

biology ecology carbon cycling mineral coal carbon cycle

  1. By giving off carbon dioxide and absorbing oxygen

  2. By giving off oxygen and absorbing carbon dioxide

  3. By releasing oxygen and carbon dioxide

  4. By absorbing oxygen and carbon dioxide.

Show answer
Correct Option: B
Explanation:

During photosynthesis, carbon dioxide is fixed to form carbohydrate by the dark reaction. The water molecules are broken down during the light reaction and release oxygen. Thus, the two process helps to maintain the balance of oxygen and carbon dioxide in the atmosphere.

So, the correct answer is option B.
