Food Chains and Food Webs
True or False: An ecosystem only includes living organisms.
False
What is human impact?
The way humans use man made tools to negatively impact the environment.
No they are not the same, a habitat is a specific place where an organism lives, while an ecosystem is a community of living organisms interacting with each other.
Name all the ecosystems.
Tundra, grasslands,wetlands, aquatic,forests, deserts.
What can a producer do?
Produce its own food.
What is the difference between a food chain and a food web?
A food chain shows one possibility how energy can flow from one organism to another in a linear sequence, while food webs have many possible ways energy can flow in an ecosystem.
Name the 3 types of pollution.
Air, water, and soil pollution.
Do nutrients cycle in an ecosystem in a continuous loop or do they stop?
Continuous loop.
What are the 3 main producers in aquatic ecosystems?
Phytoplankton, algae,kelp.
What are all the parts to a food chain?
Producer, consumer, secondary consumer, tertiary consumer, decomposer.
Can a secondary consumer eat a tertiary consumer?
No
How do fossil fuels, carbon emissions, and greenhouse gasses affect ecosystems?
Rising temperatures, altered precipitation patterns, and increased frequency of extreme weather events disrupt habitats, affect species' ranges and migration patterns, and can lead to biodiversity loss. Additionally, carbon emissions from fossil fuels contribute to ocean acidification, harming marine life and coral reefs.
If climate change were to wipe out a species of plant, would only the animal who eats the plant be affected of will the entire ecosystem be affected?
The entire ecosystem.
What are deciduous forests?
A forest with annual tree shedding during one season.
What is trophic level?
A trophic level is a position an organism occupies in a food chain or food web, representing its feeding relationships and the flow of energy through an ecosystem.
What is the animal that is at the top of the food web referred to as?
Apex Predator
How does supporting local and sustainable products impact the ecosystem?
Buying Local can reduce use of transportation and support the local community, and using sustainable products are environmentally friendly.
If an organism is in an ocean ecosystem, does it still get its energy from the sun?
In deep waters no, organisms rely on chemosynthesis, but many still do use photosynthesis higher in the ocean.
What is the average temperatures of forests (in Fahrenheit) in the summer?
70 degrees Fahrenheit.
How do mushrooms count as decomposers?
They break down dead organic matter and recycle nutrients back to the soil.
If a predator dies, will the prey's population increase or decrease?
Increase then decrease.
What are the 10 sustainable actions put into practice.
Conservation of Natural Resources, Sustainable Agriculture, Waste Reduction, Habitat Restoration, Sustainable Transportation, Wildlife Protection, Community Involvement and Education, Sustainable Fishing and Forestry, Green Building Practices, and Supporting Local and Sustainable Products.
How is reproduction different in different ecosystems?
It can be attributed to many factors such as the climate or the amount of predators there are that can cause prey to decrease and thus leaving less reproduction in some areas rather than others.
What are the lengths of short and long grasses in grasslands?
Grasses are around 7 feet with short grasses being 8-10 inches
True or False - Heterotrophs can eat other Heterotrophs.
True
