Name three biotic factors and three abiotic factors that can be seen in the food web of our ecocolumn.
100
A consumer that ONLY gets its energy from producers. Examples would be: deer, small fish, herbivores
What is a primary consumer? Give an example.
100
symbiosis
A relationship between two organisms in an ecosystem
200
Biome
One of Earth's large ecosystems with its own climate, soil, plants, and animals.
200
True! Bonus 100 points: why do we need them?
True or false: greenhouse gasses are naturally produced in the atmosphere
200
True
True or false: food webs show the transfer of energy from one organism to another.
200
aquatic producers
Algae, eloda, and duckweed are examples of _______.
200
Mutualism
What is the symbiotic relationship where both organisms are benefited?
300
Tropical Rainforest
What is a hot biome near the equator, with much rainfall and a wide variety of plant and animal life
300
Sulfur and Nitrogen
What are the two chemicals that make up acid rain?
300
Decomposers get energy from decaying organisms. Without decomposers, dead animals would pollute the ecosystem.
What is the role of decomposers in a food web?
300
secondary consumer
A mosquito fish is an example of a __________?
300
Commensalism
A symbiotic relationship where one organism benefits and one does not benefit but is unharmed
400
Tundra
A large treeless plain in the arctic regions where the ground is frozen year-round
400
Algal blooms block sunlight aquatic organisms need to live and clog waterways. Many aquatic organisms need algae as a energy source and humans can use algae for a type of biofuel.
What is one way algae can be harmful to the environment? What is one way it can benefit the environment?
400
The sun is the primary source of energy for all life. It gives energy to the producers, allowing them to go through photosynthesis.
What is the niche of the sun in a food web?
400
Chlorophyll
Producers make food using ________ to trap the sun's energy during photosynthesis. (hint: they give plants their green color)
400
parasitism
A symbiotic relationship where one organism benefits and one is harmed
500
Grassland and Savanna
A large, flat area of land with few trees and lots of tall grass. Give 2 names for full credit!
500
When too many greenhouse gasses, released by human activity, are trapped in the atmosphere, the earth temperature increases to dangerous levels.
What is the greenhouse effect?
500
False. Each organism uses up an amount of the original energy during its life, leaving a smaller amount for the next organism.
True or false: all the energy stored in a producer (example: grass) is available for a secondary consumer (example: hawk).
500
Too many consumers would use up all energy sources which could cause a food shortage. Too few producers would provide too little food sources for consumers.
Why is it important for there to be a balanced population of producers and consumers in an ecosystem?
