Answer: Option B. -> A large landmass such as a country, having different types of ecosystems such as desert, rainforest and mangrove
:
B
Ecological diversity refers to the diverse array of ecosystems being seen in a huge geographical location. India for example, has deserts, tropical rainforests, mangroves, wetlands, coral reefs, estuaries and several other types of ecosystems. Therefore, India is said to have greater ecological diversity as compared to a Scandinavian country which mostly has cold, subpolar ecosystems.

Answer: Option C. -> Amazon Rainforest
:
C
Not all places on earth are bestowed with a large variety of organisms. If we were to look at the pattern, the highest biological diversity is seen near the equator and it reduces as we move towards the poles. The Amazon forest lies in the equatorial region and hence, is one of the most biologically diverse ecosystems on the planet.

Answer: Option A. -> Conservation of wildlife
:
A
National Parks and Wildlife Sanctuaries have been established with the aim of conserving wildlife in their natural habitats. These places are protected by the forest department and they run several programmes to protect the endangered species.

Answer: Option B. -> Glucose
:
B
Since productivity is a measure of biomass per unit area, in order to gain biomass, plants need to expend energy and use the energy to generate new plant material including new cells and tissues. Via the process of photosynthesis, plants generate glucose which is stored and used later for many processes including growth and reproduction. Hence, the generation of glucose directly contributes to the generation of new plant tissue and thereby, to the generation of biomass. The measure of biomass in a given area is productivity. Although oxygen might seem like a good measure of productivity, it is released as an unintended consequence of photosynthesis. Therefore, oxygen doesn’t directly contribute to ecosystem productivity.
