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

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

If the producers in a trophic level have 300kg of biomass, how many kg of biomass would be at the secondary consumer trophic level? 3kg

The Physical Location of where an organism lives habitat

In a food web, what type of organism gives energy to all of the other trophic levels? producers

Which type of biome makes up most of the biosphere? aquatic

A group of organisms of the same species living in a particular space is a(n) population

What happens when two niches overlap Competition for resources
