Ecology
The study of interactions of living organisms with other organisms and their environment
Ecology
What does an ecosystem include?
Biotic and abiotic factors
An organisms role or job in an ecosystem
Niche
What are the primary producers in the Savanna?
Grass – they are grasslands
This is an example of a
Food Chain
Major ecosystems that occur over a wide area of land
BIOME
Typical weather pattern of an area over time is called
climate
An area that is cold and treeless
Tundra
Biome that has a dry, hot climate with little precipitation and minimal plant life.
Desert
Bogs, Marshes, and Swamps are
Wetlands
Region of life that supports all living things
Biosphere
What is the predator in this food chain?
Fox
Where is the greatest amount of energy?
Autotrophs/plants
Region of life that supports all living things
Biosphere
What is the area where fresh water and salt water meet?
Estuary
All communities, energy and abiotic factors in an area is
Ecosystem
Identify 3 abiotic factors
Rain
Sunlight
Soil
Rocks
Temperature, etc
The most common photosynthetic pigment is
Chlorophyll
What is the prey in this food chain?
Bunny
The total weight of the organisms in an ecosystem
biomass
Autotrophs make their food through which process
photosynthesis
Eats only consumers
Carnivore
What do tertiary consumers eat?
Secondary consumers
What happens if algae is removed?
All organisms would be affected
What are elephant seals (-vore)?
carnivores
What are penguins(-vore)?
omnivores
Eats only producers
Herbivore
Eats producers and consumers
Omnivore
Eats dead consumers
Detrivore or Scavenger
When a toxin is absorbed in the bottom trophic level and reaches the top of the food chain
biomagnification
Recycles nutrients back into the environment
decomposer
What is another name for a producer?
autotroph
Put the following smallest to largest: community, ecosystem, organism, biosphere, population
Organism, population, community, ecosystem, biosphere
A snake that eats a frog that has eaten an insect that fed on a plant is a
Tertiary consumer
All of the interconnected food chains make a______________
Food web

A cow is an example of a
Herbivore
A mushroom, bacteria and worms are examples of a
decomposer
A group of organisms of different species living together in a particular space is a(n)
community
When moving up the trophic levels what happens to the energy levels?
The energy decreases: 10% rule

population
What happens when two niches overlap
Competition for resources
