Ecosystems and Biomes
The living and nonliving things in one place is known as what?
An ecosystem
What are factors that can limit the growth of a population?
Limiting factors
What is the starting point of energy for producers?
The Sun
Difference between abiotic and biotic factors. Provide 2 examples of each.
Abiotic factors are the nonliving parts of an ecosystem. A biotic factor would be the living or once living parts of an ecosystem.
Abiotic- Rocks, Water
Biotic- Plants, animals
What is the largest number of individuals of one species that an ecosystem can support over time
Carrying capacity
What is the very top of a food chain known as?
Apex predators
The gradual change from one community to another community in an area
Succession
The physical place where a population or organism lives.
Habitat
What is the difference between a producer and a consumer? Provide an example of each
Producers can make their own food, consumers can not.
Producers- Plants
Consumers- Animals
What is the difference between a population and community?
A population is made up of all the members of one species that live in an area. A community is all the populations living in an ecosystem at the same time.
What is biotic potential?
The potential growth of a population if it can grow in perfect conditions with no limiting factors.
What is the difference between a food web and a food chain
A food chain models how energy flows in an ecosystem through feeding relationships
A food web is a model that shows several connected food chains
What is a geographic location on Earth that contains ecosystems with similar biotic and abiotic features?
After you answer the first question, give three examples of the answer
Biomes
Forest
Dessert
Tundra
Freshwater
Saltwater
Grassland
DOUBLE JEOPARDY!!!!! You can play for 500 or 1000. If you win you could get double points. If you lose you could lose double points. No partial points will be given. What are the three main types of symbiotic relationships, who benefits in each, and provide 2 examples of them happening. Examples must be two different types of symbiotic relationships.
Mutualism, parasitism, commensalism
Mutualism- Both animals benefit. Clownfish and sea anemones
Commensalism- One animal benefits, the other is not harmed. Dogs carrying seeds to different locations when the seeds attach to them
Parasitism- One benefits, the other is harmed. Tick and its host
Explain why in an energy pyramid there are less and less organisms as it goes higher on the pyramid.
If there were too many predators and apex predators there would not be enough food and energy to go around
