Explanation:

To solve this, we analyze each option:

• Option a: Different species can be in the same food chain (e.g., a grasshopper (one species) and a bird (another species) in a food chain like grass→grasshopper→bird).
• Option b: By the biological species concept, a species is a group of organisms that can interbreed to produce fertile offspring. Different species cannot do this (e.g., a horse and a donkey can interbreed but produce infertile mules, and most different species can't even produce offspring at all).
• Option c: Different species can live in the same habitat (e.g., many bird species live in a forest habitat).
• Option d: Different species can be in the same food web (a food web is made of multiple food chains with various species).

Answer:

b. interbreed to produce fertile offspring
