Whale calves have a high survival rate, with most calves reaching adulthood. However, their aquatic ecosystem contains a limited
amount of resources, so uncontrolled exponential growth isn’t possible. Identify the graph that represents the survivorship pattern of whales.

Answer:
The
second graph attached in the
answer shows the survivorship of whales.
</span>
The whales follow the K-strategy of reproduction. Therefore, they will typically have a high survivorship. <span>K-strategy reproduction is the production of few offspring, but heavy investment in those offspring to ensure a better chance of survival. Humans for example, usually have one baby at a time, with a long gestation, and a long period of nursing babies and caring for children.</span>

Answer:
The correct answer would be group D- 809 kg.
It can be explained with the help of pyramid of biomass.
Pyramid of biomass represents biomass or the amount of organic or living matter present at each trophic level in an ecosystem.
The amount of organic matter is usually expressed in grams per meter square (g/m²).
There are usually four trophic levels in the pyramid of biomass: primary producers, primary consumers, secondary consumers, and tertiary consumers.
Usually, the biomass decreases as we go up the trophical levels specially in terrestrial ecosystem. Inverted pyramid can be observed in case of aquatic ecosystem (biomass of phytoplanktons is less than that of herbivores).
Here, maximum biomass (809 kg) belongs to the group D and hence, it would belong to primary producers.
