Importance of Studying Ecology
1. Agroecosystems 2. Habitat creation 3. Species breeding programs 4. Wetland engineering 5. Conservation management 6. Disease transmission 7. Environmental valuation 8. Case studies 9. Endangered resources 10. New cultures and societies 11. Nature tourism
27
Reservoir
- fossil fuels - mineral in rocks sediment in oceans
28
Exchange pool
- atmosphere - soil - water
29
Biotic community
- producers - consumers - decomposers
30
- any area in the environment where materials are readily available - part of a cycle that holds an element or water for a short period of time
exchange pool
31
place where something is kept in store
reservoir
32
group of organisms that live together and interact with each other within an environment or habitat
biotic community
33
biotic community is also known as a
biota or 'biocoenosis'
34
__ (reservoir and exchange pool) + __ (organisms) = ___
physical and chemical elements + biotic = dynamic system (ecosystem)
35
self-regulating, dynamic unit composed of interacting biotic and abiotic components
ecosystem
36
Ecosystem is a ___, __ __ composed of interacting __ and __ __
- self-regulating - dynamic unit - biotic and abiotic components
37
Two characteristics of an ecosystem
1. Self-regulating 2. Self-perpetuating
38
Components of the self-regulating characteristic of an ecosystem
1. Carrying capacity 2. Maximum sustainable yield 3. Waste assimilative capacity 4. Presence of natural enemies
39
maintaining ecological balance by harmonizing the "input-output" processes that occur within it
Self-regulating
40
maximum number of individuals of a given species that a habitat can support without depleting its resources
carrying capacity
41
maximum limit of production of an ecosystem that would still allow the physical environment to recycle nutrients to support succeeding production cycles and sustain itself
maximum sustainable yield
42
ability of ecosystems to take in and recycle waste products
waste assimilative capacity
43
maintaining balance in the population of predator and preys
presence of natural enemies
44
- living components have reproductive capabilities that allow species to continue their existence - ability of the population to reproduce
Self-perpetuating
45
If not observed: carrying capacity
death of organism
46
If not observed: maximum sustainable yield
exhaustion of nutrients leading to the decline in production
47
If not observed: waste assimilation capacity
pollution
48
If not observed: natural enemies
pests
49
If not observed: self-perpetuating
extinction
50
Principles of Ecology
1. Nature knows best 2. All life forms are important 3. Everything is connected to everything else 4. Everything must go somewhere 5. Ours is a finite earth 6. Humans are stewards of nature
