I think parks play a very important “green lung “role in the cities. Say, trees in parks can breathe in carbon dioxide and breathe out oxygen that people need. People in parks can enjoy the fresh air, the amazing view, intoxicating flowers fragrance and hear birds chirping in the trees....
It's known to all that rainforests are important. But do you know why?Tropical rainforests took between 60 and 100 million years to evolve (进化) and are believed to be the oldest and most complex land-based ecosystem on Earth, containing over 30 million species of plants and animals. That...
根据第二段的“containing over 30 million species of plants and animals”可知热带雨林是三千多万种动植物的家园,故选D。 2.推理判断题。根据第三段的“Without rainforests continually recycling huge quantities of water, feeding the rivers, lakes and irrigation systems, droughts would become more common”...
). All humans and animals exhale CO2 when they breathe. CO2 is the breath of life. Animals release it to stay alive, plants absorb it to stay alive. And when animals and plants stop living and begin the natural process of decomposition, they both give off CO2. It goes i...
carbon dioxide between the oceans and the atmosphere. Animals and plants also emit CO2 through the process of respiration (breathe in oxygen, breathe out CO2). And when these plants and animals decompose, organisms within the soil respire to produce energy and emit more CO2 into the atmosphere....
Sponges are animals that belong to the phylum Porifera, which means "pore-bearing." Sponges breathe by moving water through pores, called ostia, which cover their body. Sponges respire through a process called diffusion. Simple diffusion is where chemicals, like oxygen and carbon dioxide,...

4 E They produce oxygen and absorb carbon dioxide(二氧化碳), a gas that animals,including humans, produce naturally as they breathe. But because carbon dioxide also comes from cars and factories,there is too much of it in the atmosphere, which is contributing to global warming. If everyone ...
Do all amphibians breathe through their skin? Do seed plants have vascular tissue? Can plants and animals live on mudflats? Do amphibians produce oxygen? Do phytoplankton use phosphorous? What do plants need to survive? Does water have carbon dioxide?
