Problem 2 - Biology: The Dynamic Science

Question

Which of the following accurately describes a feeding style? a. Deposit feeders obtain nutrients from organic molecules in solution. b. Deposit feeders scrape organic matter from solid material on which they live. c. Fluid feeders digest organisms suspended in water. d. Fluid feeders strain food with networks of mucus or bristles and hairs. e. suspension feeders consume sizable food whole or in chunks.

Step-by-Step Solution

Answer

None of the options given accurately describes a feeding style.

Step 1: Analyze Option A

In option A, Deposit feeders are stated to obtain nutrients from organic molecules in solution. While deposit feeders do consume organic molecules, they usually obtain nutrients by ingesting sediment and extracting the nutrients within it. Thus, this is not entirely accurate.

Step 2: Analyze Option B

Option B states that Deposit feeders scrape organic matter from solid material on which they live. This statement is more representative of Grazer feeding style, where they scrape off the material from surfaces. Hence, this option is not entirely accurate for deposit feeders.

Step 3: Analyze Option C

In option C, Fluid feeders are said to digest organisms suspended in water. Usually, fluid feeders feed on the fluid of their prey rather than organisms suspended in water. Thus, this definition is not accurate.

Step 4: Analyze Option D

In option D, Fluid feeders are stated to strain food with networks of mucus or bristles and hairs. While certain fluid feeders do use specialized appendages to acquire food, not all of them do. This option is only partially accurate.

Step 5: Analyze Option E

Option E asserts that suspension feeders consume sizable food whole or in chunks. Suspension feeders actually strain suspended particles, including microorganisms, out of water using specialized filtering structures rather than consume sizable food. So, this choice is not representative of suspension feeding.
