Relationships
This is the type of relationship between a wolf & a deer
Predator-Prey
A single member within a group
Individual (organism)
Name one abiotic factor within an ecosystem.
Rock, soil, sun, water, oxygen, etc.
An area that provides all of the resources needed to support a population
Habitat
This provides all the energy needed for the many cycles to occur on Earth.
The sun
a tick feeding off of the blood of a pig is an example of this type of relationship
This contains both abiotic and biotic factors within a specific area
Ecosystem
This is a biotic factor that can produce its own sugars/food.
Producers (plants & other photosynthetic organisms)
This type of organism makes up the base of the food web/energy pyramid. Without these, other organisms cannot survive.
Producers
Take a deep breath - what cycle did you just participate in?
A sea anemone helps the clownfish by providing a home & the clownfish helps protect the sea anemone. What type of relationship is this?
Mutualism
Reindeer, wolves, snowshoe hares, lichen, wildflowers, and other biotic factors make up this. (Not the name of the ecosystem)
Community
Which of the following are biotic? (choose 3)
Bacteria Rock
Soil Worm
Nitrogen Oxygen
Grass Metals
Bacteria, Grass, & Worm
In the following food chain, this is the second order consumer.
oat -> field mouse -> weasel -> coyote
Weasel
Some steps of this cycle are: condensation, precipitation, evaporation, accumulation, sublimation.
Water Cycle
A type of close relationship between two organisms
Symbiotic Relationship (symbiosis)
A swarm of honeybees is an example of this
population
Describe the difference between biotic & abiotic factors in an ecosystem.
Biotic- living, or once living, made of cells
Abiotic - not living, never alive, not made of cells
This type of organism breaks down dead materials and recycles the nutrients within an ecosystem
Decomposer
During this cycle, plants create a waste product that animals need, while animals create a waste product that the plants need.
Carbon-Oxygen Cycle
Birds following cattle around to eat the insects stirred up from the soil is this type of relationship. (hint: cows are unaffected)
Commensalism
All herbivores are considered this level of consumer
first-order (primary)
What are three characteristics of ALL living things?
Made of cells, grow and develop, reproduce, respond to stimuli, maintain stable internal environment (homeostasis), obtain and use energy, contain specific chemicals (like DNA)
Explain what would happen if the mountain lions go extinct in this ecosystem.
(Include at least two predictions)
Rabbit, deer, snake may increase (which could then affect the organisms that they eat)
This natural process involves conversion of a common atmospheric gas into a usable form of nutrients, such as nitrate.
Nitrogen Cycle
