Students then watch two short videos, one on niche partitioning and the other on DNA metabarcoding, and answer questions to apply what they have learned. Iss age structure diagram resembles a pyramid. Populations of some species develop adaptations that allow them to reduce or avoid competition with other species for resources; Resource Partitioning occurs when species competing for similar scarce resources evolved specialized traits allows them to share resources by using parts of them ; Consumer Species Feed on Other Species 20. In Resource Partitioning species with similar needs use similar resources: 1. at different times (hunting: hawks-day, owls-night) 2. in different ways.
