Question

1. two species of fish live in the same pond. they eat the same kinds of plants. they are eaten by the same water birds. which of the following would increase competition between these two species of fish? a average habitat temperature increases b population of water birds increases c number of food plants increases d water level in the pond decreases

Explanation:

Competition between species increases when resources are limited. If the number of food - plants decreases, the two fish species that eat the same plants will have to compete more for food. Options A (increase in temperature), B (increase in water - bird population) and D (decrease in water level) do not directly relate to the competition for their food source.

Answer:

C. Number of food plants decreases
