Ecological Relationships. Reflection question using this picture: What are some components within an ecosystem? How is an ecosystem different than a community?. What is an ecosystem?. – a community and its abiotic factors. What is a community?.
– a community and its abiotic factors
What is a community?
a group of populations that are living and interacting with one another. They are interdependent (depend on one another)
What is a population?
Communities are the building blocks of ecosystems
Biodiversity = the number of species in an ecosystem
Crucial to ecosystem productivity
Territory = space claimed by an individual organism
Required by all living things
Ecological Equilibrium = state of “balance” in an ecosystem
The role in their habitat
Ex: Fox helps control small animal populations.
- an Ecological relationship is a relationship between animals and their habitat
A niche is the sum of all activities and relationships a species has while obtaining and using resources needed to survive and reproduce
When species or individuals “fight” for the same resources.
E.g., Food, shelter….
KEYSTONE PREDATOR/SPECIES - A predator that causes a large increase in diversity of its habitat.
The “fight” may be indirect … individuals may never directly contact each other.
Losing a keystone species usually disrupts many ecological relationships.
Two species with similar needs for same limited resources cannot coexist.
A primary consumer feeds on a producer.
2. Feeding Relationships
A fruit bat eating a papaya
A woodchuck eating wild clover
Predation: actively hunting your food source (carnivory)
A lion eating zebra.
An eagle eating halibut.
