In a food chain of a grassland ecosystem, the top consumers are:

Correct option is D

The correct answer is Carnivorous.
Feeding relation in the natural surrounding:
Food Chain:
· A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat.
· A food chain shows how energy is passed from the Sun to producers, from producers to consumers, and from consumers to decomposers such as fungi.
· It also demonstrates how animals depend on other organisms for food.
Trophic Level:
· Based on the source of their nutrition or food, organisms occupy a specific place in the food chain, known as their trophic level.
· Producers belong to the first trophic level, herbivores (primary consumers) to the second, and carnivores (secondary consumers) to the third.
· An important point to note is that the amount of energy decreases at successive trophic levels.
Information Booster
Primary Producers:
· Primary producers are at the first trophic level – They produce food on their own with the help of photosynthesis.
· Examples: Plants, trees.
Primary Consumers:
· Primary consumers are herbivorous animals whose nutrition is directly based on plant products.
· Examples: Cow, deer, grasshoppers, small insects, etc.
Secondary Consumers:
· Secondary consumers are carnivorous animals.
· Examples: Small birds, wolves, etc.
Tertiary Consumers:
· Tertiary consumers are also carnivorous but they feed on secondary consumers.
So, in a food chain of the grassland ecosystem, the top consumers are carnivores.
Additional Information
· Producers: Species that produce their own food from nature.
· Examples: Plants, grass.
· Herbivores: Only consume green vegetables and plants; they are totally dependent on plants.
· Examples: Goat, rabbit.
· Carnivorous: Mainly consume secondary consumers such as rabbits, goats, etc.
· Examples: Lion, tiger.
· Omnivores: These consumers eat both plants and meat.
· Examples: Bear, pig.
· Decomposers: Organisms that break down dead materials or waste products through decomposition.
· Examples: Bacteria, fungi.
