In the context of ecology, what does the 'range of tolerance' refer to for apes?

• A. The number of different species of apes found in a given habitat.
• B. The distance apes can travel in search of food.
• C. The amount of time apes can go without water.
• D. The range of environmental conditions (such as temperature or humidity) within which apes can survive and reproduce.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the concept of 'range of tolerance' in ecology. It refers to the range of environmental conditions (e.g., temperature, humidity, pH, etc.) within which an organism can survive, grow, and reproduce. Conditions outside this range can lead to stress, reduced survival, or inability to reproduce.
2. Step 2: Relate the concept to apes. Apes, like all organisms, have specific environmental conditions they can tolerate. For example, they may have a preferred temperature range or humidity level that supports their survival and reproduction.
3. Step 3: Eliminate incorrect options. The number of species in a habitat, the distance apes can travel for food, and the time they can go without water are unrelated to the ecological concept of 'range of tolerance.' These options do not describe environmental conditions affecting survival and reproduction.
4. Step 4: Focus on the correct answer. The 'range of tolerance' for apes specifically refers to the environmental conditions (such as temperature or humidity) within which they can survive and reproduce.
5. Step 5: Apply this understanding to broader ecological contexts. Recognizing the range of tolerance helps explain why certain species are found in specific habitats and how environmental changes can impact their populations.
