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.
