Matter
How do organisms get energy and matter?
by producing their own food ( producers) and by eating (consumers)
True or false? “Energy and Matter are constantly moving through ecosystems”
True.
In what ways are plants involved in the oxygen and carbon cycles?
photosynthesis, respiration, decomposition
What is an ecosystem?
All the living and nonliving things interacting in a particular area
What is found or stored in rocks and sediments, ocean, atmosphere, and in living organisms?
Carbon
What is matter?
Matter: anything that has a mass and takes up space.
What is energy?
Energy: is the ability to do work and enable organisms to use matter in life processes.
What is process is liquid to gas?
Evaporation
Why are we NOT producers?
Because we consume substances like plants and animals to get nutrients.
how does carbon returns back to the atmosphere?
when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
Organisms use matter in body chemical processes to as digestion and for breathing.
If Energy and Matter are constantly moving through ecosystems.. so what happens to energy and to matter specifically?
1. Energy is transferred along organisms 10% rule and the rest energy is lost as heat.
2. Matter is returned to the physical environment as waste or when organisms die.
What is an abiotic matter?
Matter that makes up the nonliving parts of an ecosystem, such as air, water, and rocks
What is a primary consumer?
An organism that gets its energy from eating plants
What is a greenhouse gas?
The greenhouse gases in the atmosphere trap the Sun's heat. This makes Earth warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.The primary greenhouse gases in Earth's atmosphere are water vapor
The graphic representation in which only 10 % of energy is consumed by eating other organism is called
They energy pyramid
True or False:
Consumers breakdown solid waste product and dead organisms, returning matter to the physical environment, and the producers can then reuse this matter for life processes.
False. Decomposers like bacteria and fungi
What is biotic?
Matter that makes up the living and dead organisms in a ecosystem
Energy and matter move through organisms and the physical environment.
If we keep adding co2 in the atmosphere what can happen?
Global warming,
What happens to energy and matter in ecosystems?
Energy and Matter can’t be lost, only transformed
Can energy and matter leave ecosystems and be destroyed?
Energy and matter can leave from ecosystem when organisms move, but never destroyed.
Danielle knows that her father spread a nitrogen-based fertilizer on a patch of grass recently where the cows graze in the field. Why was it necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass?
Because plants cannot use “free” nitrogen.
Mushrooms cannot produce food through photosynthesis. Instead, they get their nutrition by digesting dead leaves and decaying organic matter. How would you classify mushrooms? Explain.
Mushrooms are classified as decomposer since they help to decompose dead organisms allowing the decaying material to go back into the food web. This means they are a type of consumer called a decomposer.
Which organisms can reduce the high amount of co2 in the earth?
Plants because they use co2 to make photosynthesis
