Need Help! on this question.. Each organism on Earth is a part of a complex relationship with other organisms. This relationship is called a food web. The following organisms are part of a food web typically located in and around a reservoir (man-made lake): {Algae; Fish; Rabbit; Eagle; Pine Trees; Grass; Field Mouse} Which of the follow combinations shows how energy flows from one organism to another in this reservoir ecosystem?
a) Fish to Pine Trees
b)Field Mouse to Grass
c) Eagle to Rabbit
d) Algae to Fish
To understand how energy flows from one organism to another in a food web, we need to identify the relationships between the organisms and the direction of energy transfer. Here's how we can analyze the given organisms and their relationships:
1. Algae: Algae are primary producers because they can take in energy from sunlight and convert it into food through photosynthesis.
2. Fish: Fish consume algae, making them primary consumers or herbivores.
3. Rabbit: Rabbits are herbivores that primarily feed on grass, making them the secondary consumers.
4. Eagle: Eagles are tertiary consumers or apex predators that feed on rabbits, making them top predators in the food web.
5. Pine Trees: Pine trees are not directly involved in the food web as they do not participate in consuming or being consumed.
6. Grass: Grass is consumed by field mice, making it part of the food chain.
7. Field Mouse: Field mice primarily feed on grass, hence becoming secondary consumers.
Now, considering the relationships between the organisms and the flow of energy, we can identify which combination shows the correct flow of energy:
a) Fish to Pine Trees: This combination is incorrect because pine trees are not part of the food web, and they do not receive energy from fish.
b) Field Mouse to Grass: This combination is correct as field mice consume grass.
c) Eagle to Rabbit: This combination is correct as eagles are top predators and feed on rabbits.
d) Algae to Fish: This combination is correct as fish consume algae and obtain energy from them.
Therefore, the correct combination showing how energy flows from one organism to another in this reservoir ecosystem is:
d) Algae to Fish
