Population Ecology: What Causes Populations to Change?

The video tutorial explores the concept of roles and niches in both human and animal habitats. It explains how organisms interact with their environment, forming ecosystems. The tutorial discusses different types of relationships among animals, such as competitive and mutualistic interactions, using examples like the oxpecker and zebra. It also covers the concept of limiting factors, which affect population sizes in ecosystems, and introduces the idea of carrying capacity, the maximum population size an ecosystem can support without degradation.

What are limiting factors in an ecosystem?

What does 'carrying capacity' mean in the context of ecosystems?
