Plants are the organisms that produce oxygen, or O2. To do this, they go through a process called photosynthesis. They take carbon dioxide, water, and sunlight, and convert it into oxygen and glucose (sugar). Without plants, you, me, your pet, and all other living organisms wouldn't have oxygen :) hope this helped!

Help me out with this three please
Vesnalui [34]
1. I’m not really sure how to answer it, i think it’s parasitic
2. The tick is the parasite since the human is the host
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)
