Ecosystems Flashcards
1
Q
in a predator-prey relationship, the predator is an:
A
organism that eats another organism (the prey)
2
Q
- symbiosis is a:
- types of symbiosis include:
A
- close and long-term interaction between two species in an ecosystem
- mutualism, commensalism, and parasitism
3
Q
- competition can occur within or between:
- resource partitioning is:
- resource partitioning can reduce:
A
- species in an ecosystem where there are limited resources
- using the resources in different ways, places, or at different times
- the negative impact of competition on survival
4
Q
- an individual is:
- a population is:
- a community is:
- an ecosystem is:
- a biome is:
A
- one organism
- a group of individuals of the same species
- all living organisms in an area (animals, plants, bacteria, and fungi)
- all living and nonliving things in an area (plants, animals, rocks, soil, water, air)
- a large area with similar climate conditions that determine plant and animal species there (ex. tropical rainforest)
5
Q
organism interactions
- competition is when organisms:
- it limits:
- it is beneficial for:
A
- fight over a resource like food or shelter
- population size (not enough resources to go around)
- neither species
6
Q
organism interactions
- predation is when:
- examples include:
- it benefits:
A
- one organism uses another for energy/as an energy source
- hunters, parasites, herbivores
- one species (the predator) but not the other (the prey)
7
Q
organism interactions
- mutualism is a:
- an example is:
A
- relationship that benefits both organisms involved
- the coral reef
8
Q
organism interactions
- commensalism is a:
- in example is when:
A
- relationship that benefits one organism and doesn’t impact the other
- birds nest in trees
9
Q
predation
- herbivores (plant eaters):
- ex.
A
- eat plants for energy
- giraffe and tree
10
Q
predation
- true predators (carnivores):
- ex.
A
- kill and eat prey for energy
- leopard and giraffe
11
Q
predation
- parasites:
- ex.
- they draw:
A
- use a host organism for energy, often without killing the host and often living inside the host
- mosquitoes, tapeworms, sea lamprey
- energy from an organism
12
Q
predation
- parasitoids:
- ex.
A
- lay eggs inside a host organism; eggs hatch and larvae eat host for energy
- ex. parasitic wasps, bot fly
13
Q
symbiosis
- sym =
- bio =
- osis =
- symbiosis =
A
- together
- living
- condition/state of being
- condition of two organisms living together
14
Q
- symbiosis is any:
- what are the three symbiotic relationships?
A
- close and long-term interaction between two organisms of different species
- mutualism (+/+), commensalism (+/0), and parasitism (+/-)
15
Q
- mutualism is a form of symbiosis where:
- better off:
- ex. coral (animals) provide:
- algae provides:
ex. lichen is a: - algae provides:
- fungi provides:
A
- organisms of different species live close together in a way that benefits both
- with it than without it
- reef structure and carbon dioxide for algae
- sugars for coral to use as energy
- composite organism of fungi living with algae; act as one organism
- sugars (energy)
- nutrients (algae to grow)
