AP Environmental Science: Unit 1 Review - Ecosystems
One species (the parasite) lives on or in another organism (the host), gaining benefits while the host is harmed. One species benefits while the other is neither helped nor harmed. Marshlands are coastal wetlands found in temperate zones, featuring non-woody, water-tolerant vegetation. They play a key role in flood control, water filtration, and habitat support.
Paratism
- one species live on /in the other (host) is harmed (+,-)
Key Terms
Paratism
- one species live on /in the other (host) is harmed (+,-)
Commensalism
- one species benefit while the other is unaffected (+, o)
Marshland
- found along the coast in temperate climates, contains non- woody merging vegetation.
Estuaries
- a coastal body of water, partly surrounded by land, with access to the open ocean and a large supply of fresh water from a river.
Symbiosis
- a long- term interaction between two species in an ecosystem.
Shrubland
- biome around California coast and the Mediterranean Sea, hot summers and mild, rainy winters, contains fire- tolerant shrubs.
