You're conducting an experiment to determine the effect of different wavelengths of light on the absorption of carbon dioxide as

an indicator of the rate of photosynthesis in aquatic ecosystems. If the rate of photosynthesis increases, the amount of carbon dioxide in the environment will decrease, and vice versa. Small aquatic plants are placed into three containers of water mixed with carbon dioxide. Container A is placed under normal sunlight, B under green light, and C under red light. The containers are observed for a 24-hour period. Carbon dioxide absorption is an appropriate indicator of photosynthesis because:_________.A) CO2 is needed to complete the light reactions.B) The energy in CO2 is used to produce ATP and NADPH.C) Plants produce oxygen gas by splitting CO2.D) CO2 is needed to produce sugars in the Calvin cycle.

Answer:

The preferable option will be - D.

D. CO₂ is needed to produce sugars in the Calvin cycle.

Explanation:

  • We know that CO₂ is the prime element for photosynthesis.
  • CO₂ is the only source that supplies carbons in this process. With the help of  CO₂, water, light, minerals, and chlorophyll, six-carbon glucose is formed.
  • This glucose is converted to starch and is stored in fruits or in the parts of plants for further use.

What is the term for a top predator that contributes to the maintenance of species diversity among its animal prey?
andreev551 [17]

Answer:

Option A, keystone species

Explanation:

Keystone species are responsible for controlling any species from becoming dominant over all other species. The keystone species are found at the top of all the energy pyramids and food chains.

They control the explosion of population of prey and hence regulate the overall ecological diversity.  

Some common example of keystone species is as follows –  

Bison, prairie dog, large mammalian predators,  

 

Hence, option A is correct
