Carrying Capacity/Limiting Factors
What is the definition for carrying capacity
Maximum population size of a species that can exist in an area/environment
Trophic pyramid must have levels in order Producer, primary, secondary, and tertiary consumer
What do the arrows show in a food web?
Arrows show transfer of energy
What is an omnivore?
Organism that eats (gets energy) from both plants and animals.
It is a shift in temperatures and weather patterns caused by human activity
Pollution, Deforestation, Climate/weather conditions, Natural disasters.
Which level of the pyramid has largest biomass? Explain why
Producers have most biomass because they are able to make their own energy using the sun.
Draw/write me a simple food web that consist the animals with the following criteria.
Plants gives energy to butterfly, Lizard get energy from butterfly. Rabbit gets energy from plants, Eagle gets energy from lizard and rabbit. Snake gets energy from rabbit.
Draw out the correct answer on Smart board.
Arrows should be pointing the correct way.
Define biomass
The total number of living organisms in a specific area
Why is climate change so bad? list 2 reasons
- less biodiversity
- Changes in ecosystem
- Less food
- Less water
Give me 3 examples of Density dependent Limiting factors
Competition, Predation, Disease, Resource availability, and Space
10%. The rest of the energy is lost as heat.
What is the difference between a food web and a food chain?
The difference is a food web show all connections and transfer of energy in an ecosystem (multiple food chains) while a food chain is just 1 linear path or one connection.
Define Species biodiversity, genetic biodiversity, and ecosystem biodiversity
Genetic - The difference in genes/traits within a population
Species - The different amount of organisms within an ecosystem
Ecosystem - The variety (different) ecosystems within an area
What are some ways we can prevent climate change? List 2
- Renewable energy
- Conserve water
- Eat more veggies
- Don't litter
Draw me a Logistic growth graph. Extra 100 points for showing Carrying Capacity as well
Reveal answer on Smart Board
What would happen to your secondary consumer if your producer increased.
There will be more secondary consumers because primary consumers will have more resources increasing population which will increase population of secondary consumers.
What would happen to the leopard seal population if the fish population decreased?
their population would also decrease because they would only have one food source to rely on (peguin)
Why are keystone species so important to an ecosystem?
Needs to have 2 of the following
-Keystone species maintain biodiversity
- Keep ecosystem stable (balanced)
- Prevents ecosystem from collapsing
What are some of the causes of climate change list 2 examples
- Burning fossil fuels
- Deforestation
- Agriculture/Livestock
- oil and gas development
- Urbanization
Draw exponential growth and tell me the difference between that and logistic growth
Why would a biologist/scientist use a trophic pyramid of a food web?
Trophic pyramid shows the different levels of energy and consumer. It also shows them in a more organized way that is easier to follow.
What would happen to the killer whale if the squid decreased?
The killer whale population would decrease by a lot because 2 sources of food (penguin and elephant seal) will lose their main source of energy.
What are some ways that keystone species can be protected? List 3 ways for full points
- Enforce/Place laws
- Reduce pollution
- Protect more of their land (Conservation)
- Educate yourself and others
- Donate to time/money to organizations
How does the greenhouse effect work?
Heat reaches earth from sun, heat is then trapped by greenhouse gasses, this cause the earths temperature to rise which in turn leads to global warming and eventually climate change.
