Question

13 mark for review which choice best describes data from the graph that support the students conclusion? a the spider population count was the same in both enclosures on day 1. b the spider population count also substantially declined by day 30 in the enclosure without lizards. c the largest decline in spider population count in the enclosure with lizards occurred from day 1 to day 10. d the spider population count on day 30 was lower in the enclosure with lizards than in the enclosure without lizards. to determine the effect of lizard presence on spider populations, a student in a biology class placed spiders in two enclosures, one with lizards and one without, and tracked the number of spiders as the experiment for 30 days. the student concluded that the reduction in the

Explanation:

Step1: Analyze option A

On day 1, the spider - population count in the enclosure without lizards is higher than in the enclosure with lizards. So option A is incorrect.

Step2: Analyze option B

The spider - population count in the enclosure without lizards does not decline substantially by day 30. So option B is incorrect.

Step3: Analyze option C

The decline in the spider - population count in the enclosure with lizards from day 1 to day 10 is not the largest decline. The decline from day 10 to day 20 is larger. So option C is incorrect.

Step4: Analyze option D

On day 30, the spider - population count in the enclosure with lizards is lower than in the enclosure without lizards. So option D is correct.

Answer:

D. The spider population count on day 30 was lower in the enclosure with lizards than in the enclosure without lizards.
