Competition and Energy Dynamics in Ecosystems
Explore the various relationships between organisms in ecosystems, including competition, predation, and parasitism. Learn about interspecific and intraspecific competition, resource competition among plants and animals, and examples highlighting the intensity of these interactions. Enhance your knowledge of energy flow and success criteria to understand the dynamics of ecosystems better.

Competition in ecosystems Energy in Ecosystems
Relationships in ecosystems Re-cap In a previous lesson 3 different relationships between organisms were studied. What were the 3 relationships? Competition, Predation and Parasitism. What is competition? Energy in Ecosystems
Today we are looking at two types of competition: Interspecific and Intraspecific Success criteria Be able to define each one. Be able to explain the difference between the two. Energy in Ecosystems
Competition When does competition occur? When organisms require the same or similar resources What type of resources do organisms compete for? Light, water, food, space, reproductive mates Competition can be either Interspecific or Intraspecific. Energy in Ecosystems
Interspecific competition This occurs between members of different species in an ecosystem who require similar resources. Examples are red/grey squirrels, brown/rainbow trout The organisms require similar but not exactly the same resources. Energy in Ecosystems
Intraspecific competition This occurs between members of the same species in an ecosystem who require the same resources. Examples are robins in a garden or rabbits in a field. This often more intense as the same resources are needed. Energy in Ecosystems
Competition Collect your question grid and find someone who can answer the question. They must sign your grid. What is competition? What is intraspecific competition? What is interspecific competition? What do plants compete for? What do animals compete for? Give an example of each type of competition Which type of competition is most intense and why? Another type of relationship between organisms? Another type of relationship between organisms? Review with the teacher Energy in Ecosystems
