Question

The graph shows the populations of two species in a particular region over two decades. Based on the graph, what can you conclude about the relationship between the two species? Graph representing the relationship between two species with time in years on the x-axis and population in thousands on the y-axis. The Lavender color wave line represents species 1 and the Red wave line represents species 2. A. The two species have a parasitic relationship. B. The two species are mutualistic in nature. C. The two species exhibit commensalism. D. The two species have a prey-predator relationship. E. The two species have a familial relationship.

Answer 1

To determine the relationship between the two species based on the graph, we need to analyze how their populations change in relation to each other over time.

In the given graph, we see that the Lavender (species 1) and Red (species 2) wave lines have opposite trends:

Lavender (species 1) population increases over time.

Red (species 2) population decreases over time.

This opposite trend suggests that species 1 and species 2 have a prey-predator relationship. In such a relationship, an increase in the population of the prey species (species 1) leads to a subsequent increase in the predator species (species 2), which then causes a decrease in the prey species, and so on. This cycle repeats over time.

So, the correct answer is option D: The two species have a prey-predator relationship.
