Paradoxically, it is also one of the hardest to define (Ecology is still a young science). In essence, an organism’s niche is how it makes a living: the environmental conditions it tolerates, the important resources it needs to survive, and its ways of obtaining those resources. In obtaining energy, nutrients, etc.. a populations of one species frequently interact with populations of other species.Ecological Relationship: Ecological Relationship is the relationship between organisms in an ecosystem with each other, the ecosystem, and the ecosystem itself with other ecosystems. No organism is an autonomous entity isolated from its surroundings. It is part of its environment, rich in living and non-living elements all of which interact with each other in some fashion. An organism's interactions with its environment are fundamental to the survival of that organism and the functioning of the ecosystem as a whole.Ecological Relationship: Ecological Relationship There are different kinds of relationships. Predation is when one animal eats another. One species benefits by getting food. The other species is killed.Ecological Relationship: Ecological Relationship Competition is when two organisms are trying to get the same resources, whether it's food, water, or sunlight. Neither species benefits from this relationship, because each organism is taking resources from the other.Ecological Relationship: Ecological Relationship Competition among members of the same species is intraspecific . Competition among individuals of different species is interspecific .Ecological Relationship: Ecological Relationship Symbiotic Relationships occur when two organisms live side by side. There are several different kinds of symbiotic relationships: Mutualism : Both species benefit. The two organisms help each other. An example would be a honey bee and a dandelion. The honey bee gets to eat the pollen from the flower. The dandelion uses the bee to spread its pollen to another flower.Mutualism: MutualismEcological Relationship: Ecological Relationship Commensalism : One species benefits. The other species is unaffected. A common example is an animal using a plant for shelter. An American Robin benefits by building its nest in a Red Maple tree. The tree is unaffected.Ecological Relationship: Ecological Relationship Parasitism : Ones species benefits. The other species is harmed. An example would be a deer tick and a White-tailed Deer. The tick gets food from the deer without killing it. The deer is harmed by losing blood to the tick, and possibly by getting an infected wound.Ecological Relationship: Ecological Relationship Neutralism : Neither species benefits or is harmed. Both organisms are unaffected. An American Goldfinch is a bird that eats mostly seeds. It may share a tree with a Great Crested Flycatcher, which eats mostly insects. Neither affects the other. Example: the tarantulas living in a desert and the cacti living in a desert You do not have the permission to view this presentation.
