What is an output?
The result or outcome of a system
100
which characteristics of life is this image showing
all organisms needs energy
100
In an ecosystem, energy is passed from producers to...
consumers
100
Ecology is the study of...
Living organisms and the way they interact with their environment and each other.
100
The 3 types of systems are...
open, closed, and isolated
200
An open system is when the input and output can do what?
the input and output flows freely through the system
200
Which of the following is NOT a characteristic of all living things?
Ability to reproduce
Ability to move
Ability to respond to their environment
Ability to move
200
How much energy is transferred to the primary consumer if the producer has 3450 joules of energy?
345 Joules
200
An abiotic factor in an ecosystem is...(list 2 examples)
non-living things, rocks, air/oxygen, temperature, water, soil, carbon
200
What abiotic factors affects a producer's ability to provide energy for the entire ecosystem?
the sun
300
A classroom is an example of a...
closed system
300
If the temperature in the environment increases and a plant starts wilting, what characteristic of life is it demonstrating?
All living things reacts to its environment
300
What is the highest trophic level in this pyramid?
tertiary
300
A BIOMASS pyramid shows how much...
dry matter/mass a population of organisms have
300
The difference between a food web and food chain is...
food chains are simple models of energy flow in an ecosystem, food webs is a complex model of energy flow and shows a more comprehensive view.
400
A food chain demonstrates that that energy in the ecosystem is part of what type of system?
open system
400
Respiration is the process in which...
Oxygen is used to break down molecules for our cells to obtain energy from our food.
400
In this image what is the bacteria?
omnivore, carnivore, decomposer, herbivore
a decomposer
400
What is the hierarchal order of ecology (smallest to biggest)
individuals -> population -> community -> ecosystem -> biome -> biosphere
400
The biosphere is an example of what type of system?
isolated or closed
500
In an ecosystem, what feedback is used to determine how much energy is available in the ecosystem?
the population size of the producers and/or consumers
500
What are the 7 characteristics of life
All living things...
needs energy
uses respiration for their cells to obtain energy
reproduce
reacts to their environment
maintain internal balance
are made of cells
grow and develop
500
To lower the amount of energy in an ecosystem, what trophic level should you eliminate and why?
the producers because they provide the total energy for entire ecosystem
500
Why is there a limited amount of trophic levels in an ecosystem?
Because energy decreases as it goes up the trophic levels. There wouldn't be enough energy to support life as you continue to increase the trophic levels.
