Answer: Clinging to the host in a parasitic lifestyle.
- A Improved locomotion specifically through open water environments
- B Clinging to the host in a parasitic lifestyle
- C Capturing prey actively using specialized grasping structures
- D Photosynthesis occurring within specialized chloroplast-containing cells
Correct answer: B. Clinging to the host in a parasitic lifestyle
Explanation: Many endoparasites like tapeworms have adhesive organs or suckers as an adaptation to cling to their host's tissues, supporting their parasitic mode of life.
Exponential growth produces an ever-steepening J-curve with no limit, an unrealistic long-term model; logistic growth produces an S-curve that levels off at the carrying capacity K, as growth rate (K−N)/K shrinks to zero once resources are fully used.
Concept context
How organisms interact with abiotic factors and respond to stress, plus population attributes, growth models, and interspecific interactions such as predation, competition, and mutualism.
