what gas is expelled by plants animals?

Answer 1

plants: o2
animals: co2 and methane

Answer 2

Plants expel Oxygen

Animals CO2, Methane etc.

Answer 3

When Breathing we expel Nitrogen, Oxygen and Carbon Dioxide.
When "passing gas" we expel Methane.
In fact Scientist look for Methane in Mars environment in search for signs of life, because Methane is the by product of bacteria, bacteria that exist in our intestines, they convert CO2 to Methane in a natural process, when this process is interrupted we have indigestion... so when you got indigestion you need to drink a lot of water and coke rich in carbons.. cool ha?

Plants expel Oxygen during the day photosynthesis and Carbon Dioxide during the night.

Answer 4

Green plants emit oxygen in daylight. Animals expel lots of types especially CO2 and whatever gas farting expels.

Answer 5

Animals expel CO2
Plants expel Oxygen in daylight, CO2 at night.

Answer 6

humans expell CO2.
Some animals expell methane gas as well (i.e. cows, other ruminants)

plants take in CO2 (thats carbon dioxide!) and through its metabolic cycle, creates O2 (oxygen) that it then expells into the world.

Answer 7

methane is expelled by both

animals expel CO2

plants expel oxygen

Answer 8

Biomass is organic material made from plants and animals. Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. The chemical energy in plants gets passed on to animals and people that eat them. Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist. Some examples of biomass fuels are wood, crops, manure, and some garbage.

When burned, the chemical energy in biomass is released as heat. If you have a fireplace, the wood you burn in it is a biomass fuel. Wood waste or garbage can be burned to produce steam for making electricity, or to provide heat to industries and homes.

Burning biomass is not the only way to release its energy. Biomass can be converted to other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel. Methane gas is the main ingredient of natural gas. Smelly stuff, like rotting garbage, and agricultural and human waste, release methane gas - also called "landfill gas" or "biogas." Crops like corn and sugar cane can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats.

Biomass fuels provide about 3 percent of the energy used in the United States. People in the USA are trying to develop ways to burn more biomass and less fossil fuels. Using biomass for energy can cut back on waste and support agricultural products grown in the United States. Biomass fuels also have a number of environmental benefits.

Answer 9

whatever may be the species the expiratory gas is always carbondioxide only. During day time as photosynthesis is active the respiratory process is low in plants. IN night time respiration is more active. BREATHING TO BE ALIVE MEANS CARBONDIOXIDE IS TO BE ELIMINATED.

Answer 10

animals: carbon dioxide, methane

plants: oxygen
