Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): First trophic level in a food chain is always a green plant.
Reason (R): Green plants are called producers.
Explanation:
Trophic Levels in a Food Chain:
A food chain is a sequence of organisms in which each organism serves as a source of food or energy for the next organism in the chain. The trophic levels in a food chain represent the different stages of energy transfer.
1. Producers (Autotrophs):
The first trophic level in a food chain consists of producers, also known as autotrophs. These are organisms that can produce their own food using sunlight, water, and carbon dioxide through the process of photosynthesis. Green plants, such as trees, grass, and algae, are examples of producers.
2. Primary Consumers (Herbivores):
The second trophic level in a food chain consists of primary consumers, also known as herbivores. These organisms feed directly on producers. Examples of primary consumers include rabbits, cows, and deer.
3. Secondary Consumers (Carnivores):
The third trophic level in a food chain consists of secondary consumers, also known as carnivores. These organisms feed on primary consumers. Examples of secondary consumers include lions, tigers, and snakes.
4. Tertiary Consumers (Top Carnivores):
The fourth trophic level in a food chain consists of tertiary consumers, also known as top carnivores. These organisms feed on secondary consumers. Examples of tertiary consumers include eagles, sharks, and humans.
Explanation of Assertion (A):
The first trophic level in a food chain is always a green plant. This is because green plants are the primary producers in most ecosystems. They have the unique ability to convert sunlight, water, and carbon dioxide into glucose and oxygen through photosynthesis. This process allows them to produce their own food and energy, making them the foundation of the food chain.
Explanation of Reason (R):
Green plants are indeed called producers because they produce their own food through photosynthesis. They are capable of synthesizing organic compounds, such as glucose, using inorganic substances like water and carbon dioxide. This ability distinguishes them from consumers, which rely on consuming other organisms for their energy needs.
Conclusion:
Both the assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A). The first trophic level in a food chain is always a green plant because green plants are the primary producers that convert sunlight into usable energy through photosynthesis. They are called producers because they produce their own food using inorganic substances.
Reason (R): Green plants are called producers.
