Answer 1

1. Because fishes have gills which can absorb Oxygen only from dissolved form in water.

2. Because plants do not perform photosynthesis at night so they only release Carbondioxide .

3. Because the energy requirement is high during physical exercise so more breakdown of glucose is required and excess Oxygen is required for this.

Answer 2

fish can't acquire oxygen from air but only from water so it dies when brought out from water
it's body is designed like that

tree undergo respiration during Night time that is it will give out co2 which is dangerous for is to Inhale


when we r running our muscles need more oxygen and energy so our breathing rate will increase to meet the demand
