Lesson 1: Earth and its Ecosystem
Habitat is the place where an organism __________.
lives
Where does all energy on Earth originate from?
The Sun
What is formed by water vapour in the sky?
Clouds
What kind of relationship involves two individuals fighting for the same resource?
Competition
What kind of biodiversity is generally desired?
High or Low?
High Biodiversity
What is the difference between BIOTIC and ABIOTIC factors?
Biotic: living components
Abiotic: non-living components
What type of organisms are able to undergo PHOTOSYNTHESIS?
Producers (Plants)
What is the phase in which water falls from clouds as rain, snow, hail?
Precipitation
What is the animal that EATS another organism called?
What is the organism that IS EATEN by an animal called?
Predator
Prey
What is the difference between HIGH BIODIVERSITY and LOW BIODIVERSITY?
High Biodiversity: LOTS of different types of species
Low Biodiversity: FEW types of species
What is the difference between a TERRESTRIAL habitat and an AQUATIC habitat?
Terrestrial: land
Aquatic: water
What is the OPPOSITE process of photosynthesis?
What is the phase in which water turns into water vapour (gas) and rises up to the atmosphere?
Evaporation
What are three (3) examples of ABIOTIC LIMITING FACTORS?
Water, Sun, Wind, Minerals, Soil, Temperature
What are three (3) things that we can do to become stewards of the environment?
Answers may vary.
Examples) take public transit, walk, bike, pick up litter, reduce your waste/plastic use, change your diet (more plant-based foods)
What are Earth's 4 spheres?
2. Atmosphere
3. Hydrosphere
4. Biosphere
What are the 4 types of consumers?
- Eats only plants
- Eats only other animals
- Eats both plants and animals
- Eats the remains of another organism
- Herbivore
- Carnivore
- Omnivore
- Scavenger
What is the phase when water falls to the ground AND accumulates in lakes, ponds, or waterways?
Collection
What kind of relationship do clownfish (Nemo!) and sea anemones have?
Symbiosis
What has happened to the average global temperature in the past few years?
Explain how this happened.
The average global temperature increased.
Lots of air pollution (from burning fossil fuels) builds up a thick 'blanket-like' layer in our atmosphere, which traps heat and thus increases temperature.
True or False:
"Human activities can ONLY AFFECT the BIOTIC features of an ecosystem."
Explain or provide an example!
False! Human activities can also affect biotic features of an ecosystem.
For example, burning fossil fuels can pollute the air and increase temperatures.
What 2 things are NEEDED for CELLULAR RESPIRATION?
What 3 things RESULT from CELLULAR RESPIRATION?
Carbon Dioxide, Sugar, Energy, Water, Oxygen
RESULT: Carbon Dioxide + Water + Energy
What is the phase in which water vapour (gas) turns into water droplets and forms clouds?
What kind of relationships are seen in the following scenario? Explain!
Cheetahs and lions both hunting for zebras
1. Competition: cheetahs and lions
2. Predation - Predators: cheetahs and lions
- Prey: zebras
What are the six (6) different threats to biodiversity?
(H.I.P.P.O.C)
Habitat Loss
Invasive Species
Population
Pollution
Overexploitation
Climate Change
