Ecology Flashcards
What is ecology?
The study of relationships between living organisms and their environment
What are four spheres of earth planet what are they made of?
Atmosphere, lithospheric, hydrosphere, biosphere The atmosphere is made up of layer of gases the lithosphere is made of rocks and minerals the hydrosphere is made of all of earths water in solid liquid and gas form the biosphere is the zone around earth where life can exist.
What is an ecosystem what are two types of ecosystems?
Any area where the living organisms interact with their nonliving surroundings aquatic and terrestrial.
What is the hierarchy of an ecosystem?
Individual, population, community, ecosystems.
What are biotic and abiotic factors that make up an ecosystem?
Biotic producers and consumers abiotic air temperature of water mineral and soils and humidity
How do biotic factors interact in an ecosystem biotic and abiotic?
The food chain and the sun giving energy to a plant.
What makes an ecosystem healthy?
When an ecosystem is bio diverse and it’s in different choices to eat one animal extinct the other animals will still have something to eat big reaction
Where does all the energy in an ecosystem come from?
All the energy in an ecosystem other animals
What is photosynthesis what organisms do it what substances are involved the word equation what is the purpose
Only producers with your plants do photosynthesis the word equation is light energy aero chemical energy for substances involved in this process is carbon dioxide and water substances produced are carbohydrates and oxygen the purpose of this is to bring energy into the ecosystem
Describe cellular respiration what organisms do it what substances are involved the word equation what is the purpose?
All living things do cellular respiration the substances involved are glucose and oxygen and it produces carbon dioxide and water the word equation is glucose plus oxygen aero carbon dioxide plus water plus energy the purpose is to cycle oxygen and carbon dioxide and create useable energy
What are the roles in the food chain?
Producers, primary consumers, secondary consumers herbivores, omnivores, carnivores
What is the difference between a food web and a food chain?
Food web is lots of different paths and has multiple food chains connected in the food chain is one path
What would happen if an organism was removed for the food chain/web effect on prey/effect on predators?
If the ecosystem is very healthy then it should not have too big of an effect if it was biodiversity but if the ecosystem was unhealthy the animal that was a predator to that animal might not have enough food and the prey to the animal might overpopulated. However if one of the producers which air plant would be consumed they would have a much larger effect
Is the transfer of energy between trophic levels efficient explain
The transfer of energy between the trophic levels is not super efficient because after it is passed on to each new animal that only get 10% of the energy from the pool plant or animal that they ate
How is energy lost from one level to another?
Only 10% of the energy is passed on to The next level that gets that energy
