Label It!
What are the 4 different spheres of the earth and what is in each sphere
Atmosphere - gases
Lithosphere - Rocky outer shell of earth
Hydrosphere - Water on earth
Biosphere - Made from all spheres, location of where life can exist
What is the difference between food chains and food webs?
Food webs are multiple food chains combined. Food chains showcase one path for predator prey relationships in the ecosystem, while food chains show multiple.
Where does all of the energy in an ecosystem originate?
The sun
The sun is the source of all energy in an ecosystem. Without the energy from the sun, the plants cannot grow and the animals would not have food to eat.
Which of the following is a correct representation of a possible food chain?
1. Frog -> Flower -> Caterpillar -> Snake
2. Flower -> Caterpillar -> Frog -> Snake
3. Snake -> Caterpillar -> Flower -> Frog
4. Caterpillar -> Flower -> Frog -> Snake
2. Flower -> Caterpillar -> Frog -> Snake
Where is most of the water located on Earth?
In the oceans
Most of the planet's water is located in the oceans as salt water. The earth's surface is about 71% covered by the oceans, and those oceans hold about 96% of all the water on earth.
Temperature, Light, Air, water, soil, and climate are all what factors in an ecosystem?
They are all Abiotic factors in an ecosystem because they are all non-living components but still play an important part in the ecosystem.
What is Fragmentation
Fragmentation is when an ecosystem is split up due to human interference or natural causes.
In an ecological pyramid, what is the organism that inhabits the first trophic level?
The organism that inhabits the first trophic level is the producers, or plants.
In an ecosystem, why is there more prey than predators?
In an ecosystem, the prey are lower down the food chain, meaning they have more food/energy which allows them to reproduce faster.
What can you learn about an ecosystem from looking at their ecological pyramid, food chain or food web?
You can learn about which predators eat which prey, what is the top predator, the different species which live in the ecosystem, etc.
A flea feeds on the blood of a mouse, in this relationship the mouse is negatively affected. What is the name of this relationship and what is a basic definition of this relationship.
This is a Parasitic Relationship, a parasitic relationship is when one organism benefits and the other is negatively affected.
Define carrying capacity?
Carrying Capacity is the capacity of living organisms that can be supported without causing harm to the earth in a singular ecosystem.
How does energy flow throughout an ecosystem?
Energy flows through an ecosystem through producers to consumers in a food chain or food web.
Which of the following is the correct order for an ecosystem, from smallest to largest?
Community, individual, population, and ecosystem
Ecosystem, individual, community, and population
Population, individual, community, and ecosystem
Individual, population, community, and ecosystem
Individual, population, community, and ecosystem
Which of the following could affect infiltration of water into the surface of the soil?
I. Concrete sidewalks
II. Roads
III. Parks and gardens
I and II
Infiltration is the process by which water can seep or be absorbed into the soil, which makes the soil wet or turns the water into groundwater. If there is something covering the soil, like a road or a sidewalk, then the water cannot be absorbed and instead sits on the hard surface.
A species is very close to becoming extinct. What label would we give this species?
This species is an endangered species
Define Commensalism and give an example
Commensalism is a relationship between two organisms where one is benefited by the other without harming or benefiting the other.
Example: Remora fish and Shark
What happens to energy as it moves up the food pyramid, from producers up to tertiary consumers?
It decreases
What is larger in an ecosystem, population or community? Give a definition for each.
The community is larger. A population is one species, a community is multiple populations.
How do human activities, such as pollution, climate change, and overharvesting, affect biodiversity and ecosystem health?
Human activities like pollution, climate change, and overharvesting can harm biodiversity and ecosystem health by damaging habitats, disrupting ecosystems, and introducing invasive species.
After the crocodile eats its prey, a bird called a plover flies in and cleans the crocodile's teeth. The plover eats the decomposing meat in the crocodile’s teeth and the crocodile gets a clean set of teeth. Label the relationship between these two animals.
This is a mutualistic relationship because both animals benefit.
What is the difference between photosynthesis and Cellular respiration?
Photosynthesis creates food for plants, while cellular respiration breaks down food to create energy for cells.
A finch eats a caterpillar. Assuming the caterpillar had 100% energy, what percentage of the caterpillar's energy will the finch be able to utilize?
10%
In a standard food pyramid, organisms are divided into trophic levels based on their means of gaining nutrients. As one moves upwards through trophic levels, the number of organisms that can be sustained decreases. This is because energy is lost between each level.
An ecological niche is what an organism does within its ecosystem. Some examples of an ecological niche could be what the animal eats and what it does to help other organisms in the ecosystem. Describe the ecological niche of a Black Bear.
Black bear:
-feeds on tender plant parts such as nuts and berries
-some insects and small animals
-carry seeds long distances in their digestive systems
-hibernate in winter
-feed insects (blood-feeding)
-hunted by people
List three invasive species in Canada.
some examples include
Eastern grey squirrel
Japanese knotweed
Gypsy moth
