Living things
What are the living things in an ecosystem called?
Biotic factors
A cold ecosystem with low temperatures and limited vegetation.
Arctic.
The main source of energy for most ecosystems and its producers.
Energy from the sun.
Omnivore?
A type of consumer that eats plants and other consumers for energy.
Give an example of a controlled experiment you could perform to prove the existence of the process of photosynthesis.
- Plant growth in light vs dark
- Aquatic plant in water producing oxygen
- Using iodine to prove the presence of starch
What is a producer?
A living thing that uses energy from the sun to survive (eg. plants).
An ecosystem with very little precipitation.
Desert.
What do plants need to have in order to go through the process of photosynthesis?
Energy from the sun, Water (H2O), and Carbon Dioxide (CO2).
Decomposer?
Organisms that break down the energy of dead plants and animals and return nutrients to the soil.
Give one example of two biotic components in an ecosystem having direct influence on each other.
One component immediately affects another.
*Answers may vary*
What type of consumer eats primarily plants for energy?
A primary consumer or herbivore.
An ecosystem that is located in lakes, rivers, and streams.
Freshwater ecosystem.
What do plants produce/release during photosynthesis?
Oxygen, and natural sugars like glucose and starch.
Scavenger?
A type of decomposer that primarily breaks down the energy of decaying carrion (animal carcasses) by consuming it's meat.
Explain how plants and ecosystems are important for preventing climate change on Earth?
Ecosystems store carbon within their soil and plant life through processes like photosynthesis. This prevents the potentially harmful element from being released into Earth's atmosphere.
A consumer (normally tertiary) that is at the top of its food chain and has little to no natural predators.
An ecosystem dominated by grasses with few trees.
Grassland.
What is Chlorophyll?
A substance in plants that captures light energy and makes plants appear green to the human eye.
Diversity?
The variety of plants and animals in an ecosystem.
Give one example of two biotic components in an ecosystem having indirect influence on each other.
One component affects another through a chain of interactions.
*Answers may vary*
What type of classification would most micro-organisms fall under?
Decomposers.
An ecosystem where land is saturated with water.
Wetland.
What is starch?
A form of stored energy in plants, produced after photosynthesis.
Interdependence?
When living and non-living components rely on each other.
Name a type of ecosystem that has a high amount of bio-complexity and explain why.
Ecosystems that have a diverse number of different species with high population sizes are the most biologically complex.
- Tropical Rainforests
- Coral Reefs
- Old-Growth Forests (Temperate/Boreal)
- Wetlands
