How does photosynthesis affect the starling?

Answer 1

Firstly: This sounds like a test question. Try reading the study material provided for your class.

The Starling's diet consists mostly of fruits and insects. As fruit-bearing plants produce energy via photosynthesis, and the majority of insects are very closely connected to the growth and propagation of plants, it stands to reason that the Starling's diet would vanish without the energy-conversion of photosynthesis.

Photosynthesis allows plants to harness the energy required to grow and reproduce. As plants grow and reproduce, they produce fruit, and provide food to insects and other animals. The insects that consume the fruit and other plant produce in turn thrive and reproduce, and themselves become food for other animals.
