In an ecosystem, can a carnivore survive without the presence of plants?
A
No, because plants provide shelter for carnivores.
B
Yes, because carnivores only eat other animals.
C
No, because plants are the primary producers in the food chain.
D
Yes, because carnivores can obtain energy from the sun directly.
Verified step by step guidance1
Understand the role of plants in an ecosystem: Plants are primary producers, meaning they convert sunlight into energy through photosynthesis, forming the base of the food chain.
Recognize the dependency of herbivores on plants: Herbivores consume plants to obtain energy, and they are a crucial food source for carnivores.
Identify the role of carnivores: Carnivores are secondary or tertiary consumers that rely on herbivores (or other carnivores) for energy.
Consider the energy flow in an ecosystem: Energy flows from the sun to plants, then to herbivores, and finally to carnivores. Without plants, the energy flow would be disrupted.
Conclude that carnivores cannot survive without plants: Since plants are essential for the survival of herbivores, and herbivores are necessary for carnivores, plants indirectly support carnivores by maintaining the food chain.
