Ecological organization & biomes
What are the levels of Organization?
Organisms, Populations, Communities, Ecosystems, Biomes, and Biosphere
What is an Autotroph?
An organism that produces it's own food using sunlight (plants).
What is a parasitic relationship?
A connection between an organism where one thrives and the other usually is harmed.
What is the Carbon/Oxygen cycle usually used during?
Plant's photosynthesis.
What is a non-native species also called?
An Invasive species.
What is a Biotic v. an Abiotic factor?
Biotic organisms are living structures (animals, plants, fungi, etc.) and Abiotic organisms are nonliving structures (rocks, soil, sand).
On a food chain does the arrow point from the predator to the prey or from the prey to the predator?
The arrows point from the prey to the predator.
What is a mutualistic relationship?
A relationship between organisms where they both benefit.
How important is the Nitrogen Cycle?
Very, we need the nitrogen cycle for essential components within amino acids such as DNA and RNA.
What are the three things needed for an organism to be invasive?
Easy survivability in new area, Reproduces quickly, and it must harm property or other organisms.
What biome is most commonly found close to the equator?
The Tropical Rainforest Biome.
How many trophic levels are usually represented in a food chain?
At the max four.
What is predation?
The process in which one organism (the predator) thrives and the other (the prey) is harmed.
What is Percolation?
Percolation is when water soaks into soil and fills the space between rocks and sand.
What is a threat to Biodiversity caused by humans using pollution?
Climate Change and Eutrophication.
What aquatic biome consists of both salt and freshwater?
Estuary Biomes
How much energy is lost between organisms as the trophic levels increase?
10% of energy is lost between each trophic level beginning at 100% (autotrophs) and decrease to 10%, 1%, .1%, etc.
What relationship between organisms causes both to become harmed?
Competitive relationships
What are the three components of the Biogeochemical Cycle?
Carbon/Oxygen Cycle, Nitrogen Cycle, and the Water Cycle.
What is Primary Succession?
When life begins on an area of land that has never been inhabited before.
What is an example of a Terrestrial biome
Grasslands, Tundra, Taiga, Deciduous Forest, Tropical Rain Forest, Desert,
What happens to the rest of the energy as it moves up the Trophic Levels?
The rest of the energy is usually used up or lost as heat energy.
What is an example of limiting factor?
Natural disasters, Introduction of non-native species, and human activity.
How does photosynthesis help animals and humans?
Photosynthesis removes some Co2 from the atmosphere and turns it into oxygen so we can breath.
What is happening to the Ozone layer?
