Biotic vs. Abiotic
What factor are rocks, water, and sunlight ?
Abiotic
One bacteria is a....
Organism
Two organisms fighting over the same resource is called?
Competition
This relationship benefits both organisms.
(+,+)
Mutualism
What is a factor that restricts population growth.
Limiting factor/ resource
A cactus depends on sunlight and water. What type of factors are these?
Cactus - biotic
Sunlight and Water - Abiotic
Martin is taking a quiz and is asked to write the correct order of ecosystem hierarchy. His response: population ----> ecosystem -----> organism -----> community.
His twin feels like he messed up, but martin feels like twin is glazing him? Who is right and what corrections if any need to be made?
Twin, Organism - Population - Community - Ecosystem
A lion hunting a zebra is an example of this relationship.
Predator - Prey
A mosquito is a...
Parasite
A drought affecting plant growth is an example of this type of limiting factor.
Abiotic
A lizard eats insects and hides under rocks. Identify all biotic and all abiotic factors in this scenario.
Lizard and insects - biotic
Rocks- Abiotic
Removing abiotic from an ecosystem would change the ecosystem into a....
Community
Two birds eating from the same berry bush is an example of?
Competition
Squirrels, birds, and spiders build their nests in trees, this has no effect on the tree. This relationship would be considered ?
Commensalistic
A chameleon is able to blend into its environment better than other lizard or similar organisms this is a?
Adaptation
In a pond, algae grow rapidly due to increased sunlight. Which type of factor allows the algae to grow rapidly? Abiotic or Biotic and why?
The sunlight is an abiotic factor because it is nonliving and allows rapid growth of the algae
All frogs living in the same pond are a....
Frogs, fish, insects, moss and plants together in a pond are a ...
Toads, rocks, frogs, fish, insects, water, and plants together in a pond are a ...

Why does competition increase when resources become limited?
What is a limited resource and how does it affect population size?
More organisms must fight over fewer resources
Limited resource means there is a certain or capped amount of a resource organisms need to survive.
The less there is the more competition and the less the population can grow/live?
Explain how mutualism can increase survival for both organisms.
Both organisms will gain resources, protection, or other survival abilities improving survival chances?
Give an two example of a advantageous or disadvantageous variation amongst an organism or population?
Example - Giraffes with longer necks have adapted to survive better (advantageous)
Shorter neck giraffes (disadvantageous)
A scientist removes all plants from an area. Explain how this affects both biotic and abiotic factors in the ecosystem.
Biotic factors (consumers/populations that eat plants) (i.e herbivores) decrease (less food/organisms) and abiotic conditions may change (less oxygen, soil changes)
Explain why a population is not the same as a community using an example.
pop - same species
community - different / multiple...
A new species enters an ecosystem and uses the same food as another species. Predict the impact on both populations.
Populations may decrease due to increased competition
Compare parasitism, commensalism, and mutualism by explaining one key difference in each.
Parasitism harms one organism while the other benefits, while commensalism does not, and mutualism benefits both
A mutation makes a frog brightly colored in a dark forest. Is it advantageous or disadvantageous? Predict how this affects survival and explain why.
Disadvantageous and the survival rate decreases because it is easier for predators to see?
