A pond ecosystem consists of various organisms, including algae, tadpoles, frogs, and birds. Suppose the amount of sunlight reaching the pond decreases significantly over a period of time, causing a reduction in the population of algae. With less algae available as a food source, which other organisms in this food web are likely to be most directly affected and why?

All organisms in the pond ecosystem would be equally affected because they are all interdependent and a change in one population would directly affect all others.

The algae would be most directly affected because they rely on sunlight for photosynthesis, and with less sunlight available, their population would likely decrease.

The frogs would be most directly affected because they feed on tadpoles, and with less tadpoles available, their population would likely decrease due to starvation.

The birds would be most directly affected because they feed on both tadpoles and frogs, and with less of these available, their population would likely decrease due to starvation.

The tadpoles would be most directly affected because they primarily feed on algae, and with less algae available, their population would likely decrease due to starvation.
