Definitions
What is an ecosystems?
Ecosystems are systems with abiotic and biotic components that interact.
A part of the planet, including water, land, and air.
Biosphere
Explain how photosynthesis works?
carbon dioxide gas + water + sunlight --->glucose + oxygen gas
What is competition?
Competition is the interaction between two or more organisms competing for the same resource in a given habitat
What is ecology?
The study of how organisms interact
What are two types of biomes?
2. Aquatic
What are the different nutrient cycles?
1. Water Cycle
2. Nitrogen Cycle
3. Carbon Cycle
What is predation?
Predation occurs when one organism eats another organism to obtain food
What is a biome?
A biome is a geographical region that contains similar ecosystems
What are the 5 types of territorial biomes?
1. Deciduous forests
2. Boreal forests
3. Tundra
4.Grasslands
5. Temperate coniferous forests
Explain the cellular respiration process.
glucose + oxygen gas ---> carbon dioxide gas + water + energy
What is symbiosis?
Symbiosis is a close interaction between two different species in which members of one species live in, on, or near members of another species
What is photosynthesis?
Photosynthesis is the process plants use to capture sunlight
What are the three layers of biosphere?
2. Lithosphere
3. Hydrosphere
Give an example of a nutrient cycle.
Carbon dioxide is exhaled by a wildebeest. The carbon contained in the carbon dioxide is now in the atmosphere, an abiotic part of the ecosystem. The carbon dioxide is then absorbed by a grass plant, and the carbon particle it contains becomes part of a carbohydrate in the grass’s cells. The carbon is now once again in the biotic part of the ecosystem.
What are the three main types of symbiosis?
1. Mutualism, both species benefit from the symbiotic partnership
2. Commensalism occurs when one species benefits from a relationship with another species without any harm or benefit to the other species
3. Parasitism occurs when one species benefits at the expense of another species
What is cellular respiration?
Cellular respiration is the process plants use to obtain the energy from glucose
How do marine biomes differ from freshwater biomes?
Marine: higher salt concentrations
Freshwater: lower salt concentrations
What is the difference between a food chain and food web?
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem
What is a factor that affects population?
Various answers
