Symbiosis
The combined portions of Earth in which all living things exist is called the _____________ ?
Biosphere
A place where interactions happen between organisms (biotic) and their environment (abiotic) is a/an __________________?
Ecosystem
What do you call an organism who can be found at ALL levels of an Energy Pyramid?
Decomposer
Give me 3 limiting factors in an ecosystem.
food, water, space, disease, humans, predators, etc.
What is Intraspecific Competition & give an example.
Competition within the same species. Mating, Plants competing for sunlight, etc.
Give an example of a parasitic relationship.
Ticks, tapeworms, beetle on plants, etc.
What 4 factors control the size of a population? (HINT: They are not limiting factors in the environment)
Birth/Death Rate
Immigration/Emigration
What are the 3 types of Dispersion populations can be found in within an erea?
Clumped, Uniform, Random
What are 3 types of consumers?
Types of consumers are omnivores, carnivores, herbivores and decomposers.
What is Primary Succession?
When an ecosystem starts from a place where there was only rock.
All of the members of a particular species that live in one area are called a(n)
Population
The number of individuals an environment can support over a long period of time is the ___________?
Carrying Capacity
What do you call an organism at the top of the food chain or energy pyramid?
Apex Predator
Give 2 ways Carbon is released into the atmosphere and 2 ways it is taken out of the atmosphere
Released - Fossil Fuel, Deforestation, Cell. Respiration, etc.
Taken out - Photosynthesis, Dissolved in the Ocean, Dead organisms compacted into the ground
Give an example of something that would cause Secondary Succession.
Wildfires, Floods, Farming, Logging, Tornado, Etc.
Give 3 examples of Abiot & Biotic factors
Abiotic - Sunlight, Temperature, Rock, Etc.
Biotic - Plants, Fish, Deer, Etc.
The study of organism and their interactions within and with their environment is __________ ?
Ecology
How do producers grow?
Photosythesis
What is Interspecific Competition & give an example
Competition between different species. Predation, Birds looking to nest, Invasive/Non-invasive species competing for space and nutrients.
Many individuals are born at once, but most die before reproductive age and few survive for a long period of time.
A symbiotic relationship in which both species benefit (+/+) is _________ ?
Mutualism
Since the development of modern agriculture and medical advances, the human population has shown which type of population growth?
Exponential Growth
What is the 10% rule? Give 3 reasons why this happens.
Only 10 % of energy is available to the next trophic level (consumer).
1. Not all the organism is consumed
2. The organism is using it energy
3. Energy is lost to the environment as heat
What is the main difference between a Primary Consumer and Secondary Consumer?
The difference is primary consumers are herbivores and secondary consumers are carnivores or omnivores.
Give and Example of a Type I Survivorship Curve.
Humans. Many will live past reproductive age and will start to die off as they get older.
