Across
- 5. Organelle found in all organisms that is the site of aerobic cellular respiration
- 8. Plants remove CO₂ from the atmosphere in order to produce sugar for survival
- 9. The burning of fossil fuels release CO₂ into the atmosphere
- 10. Substances in food that organisms need to grow, to repair itself, and to supply the body with energy
- 12. Process of converting nitrogen gas from the air into ammonia, done by nitrogen-fixing bacteria
- 13. An organelle found in plant and algae cells where photosynthesis occurs
Down
- 1. The process that releases energy (ATP) by breaking down glucose. (converts food molecules (glucose) into a form usable (ATP) by the organism); releases CO2< into atmosphere.
- 2. The process where ammonia (NH3) is converted to nitrate ions (NO3)- by bacteria in the soil
- 3. plants of the bean and pea family, with seeds that are rich in protein, many contain nodules of nitrogen-fixing bacteria or fungi on their roots
- 4. C6H12O6; A simple sugar that is an important source of energy
- 6. converts ammonia (from waste) into nitrate and nitrite which producers need to make proteins
- 7. Dead plants and animals transfer carbon into the earth
- 10. the atmosphere's most abundant element making up 78% of the volume in the troposphere.
- 11. Bacteria convert/change the nitrates in soil or water to nitrogen gas and release it back into the atmosphere.
