Question

1. after the tiny organisms that eat algae died, the next thing to happen would be that _______.

a. the fish would die
b. plants would lack carbon dioxide
c. humans would go hungry
d. larger animals would have less food

Explanation:

In an ecosystem, tiny organisms that eat algae (primary consumers) being a food source for larger animals (secondary or higher consumers). If these tiny organisms die, the immediate next impact is that larger animals relying on them for food will have less food. Option a (fish die) is a later consequence. Option b (plants lack CO₂) is unrelated as algae - eater death doesn't directly affect plant CO₂. Option c (humans go hungry) is a very indirect and later effect. So the most immediate next thing is larger animals having less food.

Answer:

d. larger animals would have less food
