Intro to Ecology Flashcards
Oragnism
Any living thing
In which biome would you find permaforst?
Tundra
Which ecosystem receives no sunlight?
Deep Ocean
Why is excessive nitrogen bad for an aquatic environment?
Excessive nitrogen causes the algae to grow out of control and can make it block out the sun for other plants.
True or False:
Plants and animals are able to use nitrogen gas.
False, bacteria needs to convert the nitrogen gas into a usable form first, then plants can take it in through their roots and animals get it by eating plants, or other animals that ate plants.
Give the three ways represented in the diagram that release CO2 into the atmosphere.
1 - waste and decay
2 - respiration
3 - combustion
Abiotic factor
The nonliving parts of an environment
Fill in the missing terms.
1 - evaporation
2 - transpiration
3 - respiration
4 - condensation
5 - precipitation
6 - run off
7 - saturation
What biome is represented by the graph?
Boreal Forest
or
Taiga
In what biomes would you expect plants with small needle-like leaves?
Boreal Forest/Taiga and or the Desert
What biome is in the picture?
The Tundra
What step goes in the blank in the picture of the Nitrogen cycle?
Consumption
Which biome has nutrient rich soild but very few trees?
Grassland
Examples of Carbon sinks
Forests, the ocean, fossil fuels,
Biome with the greatest diversity
Rain forest
Biome
Groups of Ecosystems that share similar climates and organisms
Give the three processes, represented in the diagram, that release water into the atmosphere.
1 - evaporation
2 - transpiration
3 - respiration
Combustion
The burning of fuel.
What biome is represented by the graph?
Tundra
Where would you expect to find this animal?
Deep Sea
Transpiration
The process of water being released from a plant into the atmosphere.
What biome is represented by the graph?
Desert
Carbon Sink
A natural environment that absorbs and stores more CO2 than it releases
What biome is represented by the graph?
Rain Forest
What biome is represented by the graph?
Polar
Which biome has 4 seasons?
deciduous forest
biotic factor
The living parts of an environment
What are the main necessities of life?
Food, water, shelter/space, climate
What process fills in the blanks on the diagram?
Photosynthesis
Ecology
The study of organisms and how they interact with each other and their environment
Connection between the carbon cycle and the oxygen cycle
One cycle cannot exist without the other. Plants depend on animals releasing carbon dioxide and animals rely on plants turning carbon dioxide into oxygen
What do the dots in the diagram represent and what is the process they use to convert nitrogen gas to usable nitrogen?
The dots represent bacteria and the process used is called nitrogen fixation.
Nitrogen Fixation
The process of turning nitrogen gas into a usable form
What difference would you expect to see between the climate graphs of the rain forest and a deciduous forest?
For the deciduous forest the precipitation would be less than in the rain forest, and the temperature would fluctuate much more.
Eutrophication
A natural process in a body of water when it builds up a concnetration of nutrients which speeds plant growth and eventually chokes out all life creating a “dead zone”
Fossil Fuels
Buried remains of organic materials that over a long period of time change into fossil fuels like coal, oil, natural gas.
Habitat
The specific area in which an organism lives.
What biome is represented by the graph?
Deciduous Forest
What biome is represented by the graph?
Grassland
Fill in the missing terms
1 - photosynthesis
2 - waste and decay
3 - respiration
4 - combustion
Climate
The annual precipitation and temperature.
In what biome would you expect to see mainly coniferous trees?
Boreal Forest
or
Taiga
What causes a dead zone?
When the nutrients build up it causes algae to grow and block the sun from submerged plants. Those plants die and cause the oxygen leves to drop, eventually causing all life that connot leave to die.
How does temperature affect an environment?
Temperature determines the type of precipitation it will get, the adaptations required by plants and animals
