Levels of Organization
What do we call one individual living thing?
Organism
An ecosystem consists of living things interacting with ______________.
Physical Environment
The area where an organism lives.
Habitat
An organism that makes its own food
Producer
The movement of soil by water, wind, or ice.
Erosion
A group of organisms of the same species living in the same area.
Population
Cattle, grass, bacteria, and insects are examples of this type of ecosystem factor.
(Abiotic of Biotic)
Biotic Factors
The role or position an organism has in its environment.
Niche
An organism that gets energy by consuming other organisms.
Consumer
Water moving across the land that can carry soil, waste, and nutrients.
Runoff
All of the different populations living and interacting in an area.
Community
Soil, rocks, water, air, and sunlight are examples of this type of factor.
Abiotic Factors
In this ecological relationship, two or more organisms use the same limited resources such as food, water, or space.
Competition
In this food chain, identify the producer: Wheat → Grasshopper → Chicken
Wheat
The responsible use and protection of natural resources.
Conservation
This is the largest level of ecological organization and includes all areas of Earth where life exists.
Biosphere
Name the four types of ecosystems you need to know.
Terrestrial
Freshwater
Saltwater
Artificial
One organism pursues and consumes another organism for food.
Predation
This model shows many interconnected food chains.
Food web
This conservation practice involves planting crops to cover and protect the soil.
Cover cropping
Put these in order from smallest to largest: Biome, Organism, Ecosystem, Population, Biosphere, Community.
Organism → Population → Community → Ecosystem → Biome → Biosphere
A farm is considered this type of ecosystem because humans have created and manage it.
Artificial Ecosystem
Identify all three symbiotic relationships and their effects: +/+, +/-, and +/o.
Mutualism: +/+
Parasitism: -/+
Commensalism: +/o
Name four of the nine elements found in the farm ecosystem.
Water, Soil, Air, Water, Livestock/Animals, Plants, Insects, Decomposers, Farmer
Name three conservation practices besides cover cropping.
No-till farming, Fencing/Feeding Areas, Buffer zones
