Question

a scientist wanted to know how tadpole population density (i.e., the number of tadpoles per volume of water) affects the average body weight (in grams) of a tadpole in that population. four different tadpole population sizes were chosen (15, 60, 240, and 480), and the populations were stocked in 4 separate but identical 3 l glass aquariums. food, temperature, and light were kept constant, and all the tadpoles weighed 0.04 g at the start of the experiment. the graph shows the results of the experiment after 10 weeks. what can be concluded from the graph? the tadpoles gained body weight faster when the population size was smaller. the body - weight gained by the tadpoles per week was the lowest when the population size was 15. the body - weight gained by the tadpoles per week was the same for population sizes 240 and 60. the tadpoles gained body weight faster when the population size was larger.

Explanation:

Analyze the graph to see the relationship between population size and average body - weight gain over time. The line representing the smallest population size (15 tadpoles) has a steeper slope in the initial period, indicating faster weight gain compared to larger population sizes.

Answer:

The tadpoles gained body weight faster when the population size was smaller.
