What is the difference between a food web and a food chain?
A food chain shows a linear path of energy flow while a food web shows multiple paths for multiple species.
100
The number of organisms of ONE species within an ecosystem are called
What is a population
100
What is a limiting factor that only affects producers?
What is the amount of sunlight
100

Are mutations random? 

yes
100
What does biodiversity allow an ecosystem to do?
What is be more stable and be controlled.
200
Which one has higher biodiversity? A food chain or a food web? why?
A food web has a higher biodiversity because more species are involved.
200
All of the populations in an ecosystem are called
What is a community
200
How can you increase the carrying capacity of a certain population in an ecosystem?
What is remove the limiting factors.
200

What is natural selection

Species best adapted to their environment are able to reproduce

200
Why is it better if a farm plants a variety of crops instead of just one crop.
What is if there is only one crop and a bacteria/pathogen attacks that one crop, the entire farm ecosystem will be devastated.
300
What will happen to an ecosystem's carry capacity for herbivores if producers are destroyed?
What is the carrying capacity will decrease because now they don't have enough of the food they eat.
300
An ecosystem is different from a community because
What is an ecosystem contains both abiotic and biotic factors.
300
If there is enough CO2 for ten trees, enough water for 50 trees, and unlimited amounts of sunlight... what is the limiting factor?
What is CO2 because there is only enough for ten trees.
300

What is an adaptation? 

Any inherited characteristic or trait that increases an organism's chance for survival. 

300
Why does it make sense that producers have a higher biomass than tertiary consumers?
What is they have access to unlimited energy... sunlight energy.
400
What happens to the carrying capacity of primary consumers if all of the tertiary consumers are hunted by humans?
What is the carrying capacity will decrease because the number of secondary consumers (predators) will increase and they will become the limiting factor.
400
Why does only 10% of the energy get passed on to the next trophic level in an energy pyramid?
What is the organism needs to use some of the energy and a majority is lost to the environment as heat.
400
Will species always be exactly at the carrying capacity (i.e. if the carrying capacity for rabbits is 10, will there always be only 10 rabbits in the ecosystem?)
What is no, it will fluctuate around the carrying capacity.. sometimes it will be higher, other times it will be lower. REMEMBER: Animals don't know that an ecosystem has a carrying capacity.
400

Name three evidences for common descent? 

DNA, Homologous anatomy, embryology, fossil record

400
Why is it incorrect, even though we say producers have more energy available, that 1 corn has more energy than 1 cow?
What is 1 corn weighs much less than 1 cow. You must compare equal amounts of weight. 10 lbs of corn vs. 10 lbs of beef.
500
What is worst: All of the producers being removed or all of the tertiary consumers being removed?
What is the producers because without producers we wouldn't be able to convert sunlight energy to organic energy (glucose).
500
Ecosystems are always aiming to be stable, What is one thing that can make an ecosystem unstable.
What is Natural disaster, negative human activity, invasive species, too many predators, too few prey, producers are destroyed, or disease.
500
What is a population that doesn't have a carrying capacity? Why doesn't it?
What is humans because none of the limiting factors controls the population size.
500

True or false- Populations evolve not individuals

true

500
Why are invasive species bad for an ecosystem? Answer in terms of biodiversity.
What is they out compete the native species and take all the resources. which leaves little resources for the native species, and their carrying capacity goes down. This means biodiversity is lowered.
