Just a Mix of Stuff
the networks of interactions that link the living (biotic) and non-living (abiotic) elements of the environment together ..is the definition of this term.
What is Ecosystem
is an interaction between individuals of different species in which one benefits and the other is harmed
What is parasitism.
All ENERGY on the Earth starts from this and passes on from one organism to the next.
What is the Sun.
True or False? humans frequently do not interact with ecosystems in a sustainable way
True
the two types of cycles we covered.
Carbon Cycle and Water Cycle
A species is defined as this.
What is a group of organisms that can successfully REPRODUCE among themselves.
Nemo and his dad, both silly clownfishes, live in a sea anemone. The type relationship they have with the sea anemone is this.
What is mutualism (both protect each other from predators and provide food for each other in some way).
These animals eat only producers.
What is an herbivore.
How is biodiversity related to ecosystem health?
the greater the biodiversity, the healthier the ecosystem
This process takes Carbon out of the atmosphere
what is photosynthesis
List 4 examples of ABIOTIC elements
(any four things that are found in ecosystems that are non-living. ex, sunlight, air, snow, sand dunes, rock, dead animals/plants)
Ecosystems are interactions between these two factors.
What is abiotic (non-living) and biotic (living) factors.
These organisms are the first to grow in Primary succession 1) ____. They are made of two types of organisms : 2) _____ & ______
1) Lichens, 2) Fungus and Algae
Compare and contrast Evaporation and Condensation 1)____, and which cycle are they from? 2)__
1) Evaporation is water turning from liquid to vapour (gas is ok), returning to the atmosphere. Condensation is water forming the tiny water droplets in clouds (vapour/gas to liquid).
2) Water cycle
Succession is a process by which new species gradually replace old species in an ecosystem. This type of succession happens often after a natural disaster (ex: hurricanes, tornadoes, forest fires) and does not take as long as the other type of succession.
What is secondary succession.
An interaction where plants in a the same meadow want the same nutrients in the soil, the same water and the same sunlight.
What is competition?
Here is a food chain: sun-->grass-->mouse-->snake-->hawk Which organism would have to exist in the LOWEST numbers for this food chain to be sustained?
What is the hawk.
is a species that has been introduced to an area (accidentally or on purpose) where it did not exist before, and causes harm; 1) _____. An example is 2)____
1) Invasive species, 2) Zebra Mussels, (many more)
What is the biggest way that humans impact the carbon cycle?
humans are having a major impact on the carbon cycle because of the amount of fossil fuels that they burn
What are the FIVE basic needs of living things?
1. Sun
2. Air
3. Water
4. Food
5. Ideal Temperature Range
This type of relationship/interaction is when animals hunt other animals for food 1)_____. The example from our notes (the graph), is the 2) _____ (hunter) and the 3) ______(hunted).
What is 1) predation; 2) lynx; 3) hare/rabbit
1) _____ __ _____ - Tells us exactly how much ENERGY is consumed at each level. If we want to know how many organisms are at each level, we need to look at this: 2) _____ __ _____.
What is 1) pyramid of energy; 2) pyramid of numbers.
What is Succession? 1) ______ and how can humans impact it? 2) _____ (give example)
1) a series of gradual changes that result in the replacement of one community of plants and animals by another (there are two types
2) many ways - example, can cause it (forest fires, clearcutting trees), can accelerate it (helping to plant trees), can interfere with in (introduce invasive species)
List two ways carbon dioxide is returned to the atmosphere.
Combustion (burning fossil fuels), and cellular respiration.
