This organism makes its own food using sunlight.
Producer
Producers occupy this trophic level.
1st trophic level
What is the name of non-living parts of an ecosystem?
abiotic
What is Biodiversity?
The variety of living organizms in an ecosystem
What is the definition of sustainability?
Using resources so they remain available for future generations.
a _______ _______ shows one feeding path of organisms. Hint: It is smaller than a food web.
A food chain
Deer belong to this trophic level.
Primary consumers
What is the name of the living parts of an ecosystem?
Biotic Factors
Human activities such as habitat destruction can occur how?
Deforestation, urbanization, and agriculture
If a First Nations community has been able to harvest salmon for over 1000 years, what are they doing right?
sustainable harvesting, taking what they need but also ensuring the population doesn't run out.
In the food chain Algae → Crayfish → Yellow Perch → Great Blue Heron, this organism is the primary consumer.
Crayfish
Wolves belong to this trophic level
secondary consumers
Give one Abiotic factor that can be found around Opeongo Highschool
sunlight, water, soil, air, temperature
Burning fossil fuels increases the amount of this gas in the atmosphere.
carbon dioxide (CO2)
Clear-cutting forests impacts atmospheric CO₂ because trees normally do what specific funtion?
absorb carbon dioxide through photosynthesis
In the food chain Algae → Crayfish → Yellow Perch → Great Blue Heron, if the population of rabbits decreases, this predator may also decrease due to a lack of food.
Coyote or hawk
Most energy in the food chain is found at this trophic level
1st trophic level
This process allows plants to convert sunlight into chemical energy
photosynthesis
Excess fertilizer runoff can cause this problem in lakes and rivers
algae blooms or eutrophication
The sun
Create a Food chain that includes a producer, herbivore, and carnivore.
An example may be grass, a mouse, a hawk
What are the three types of consumers and what do they eat?
herbivores - plants, carnivores - meat, and omnivores - plants & meat
This process releases energy from glucose in cells
cellular respiration
Increased fishing may cause what problems for the ecosystem?
food chain destruction, habitat destruction, unintentional catching of other species, genetic weakening
How does energy enter a food chain?
producers capture sunlight through photosynthesis and convert it into chemical energy
