Autotrophs are organisms that produce their own food through a process called photosynthesis. They are the primary producers in a food chain, serving as a source of energy for other organisms.
Option A: Apple Tree
- Apple trees are autotrophs because they have chloroplasts in their leaves, which contain chlorophyll, a pigment necessary for photosynthesis.
- They convert sunlight, carbon dioxide, and water into glucose and oxygen.
- The glucose serves as their food source, while the oxygen is released into the atmosphere as a byproduct.
Option B: Frog
- Frogs are heterotrophs, which means they obtain their food by consuming other organisms.
- They are consumers in the food chain and rely on autotrophs or other heterotrophs for their energy needs.
Option C: Mushroom
- Mushrooms are not autotrophs.
- They are fungi, which are heterotrophic organisms that obtain their nutrients by decomposing organic matter.
- Mushrooms play a vital role in recycling nutrients in ecosystems but do not produce their own food.
Option D: Eagle
- Eagles are heterotrophs and are classified as secondary consumers in the food chain.
- They obtain their energy by consuming other animals, such as rodents or fish.
In conclusion:
- The autotroph in the given options is the Apple Tree (Option A). It produces its own food through photosynthesis, making it a primary producer in the food chain.
