It should be (D) I believe A goes with T and G goes with C
Say you have GTA it would be CAT

Explanation:
All the others happen in mitosis.
These two organisms may have evolved by coevolution. The last option in the given question is the correct option. The Latin-American humming birds had to evolve as per their surroundings, otherwise they would have become extinct in that region. For that sole purpose they had to have the long and curved bills. The flowers needed the humming birds for their pollination. To attach with the legs of the humming birds in the region, the flowers had to become sharply curved. The humming birds had to come in contact with the flower while sucking the nectar. this helped the plants in their pollination process. so both became mutually beneficial to each other.
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.
