Answer;
A) respiration of living organisms.
D)absorption of CO2 from the atmosphere by ocean water.
Explanation;
-The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion.
-Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration. Respiration and combustion - burning - both release carbon dioxide into the atmosphere.
B. Ice-albedo feedback
Explanation:
The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo.
Albedo is the ratio of reflected light to incident light.
A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation.
Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice.
Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c
How does a low albedo relates to increase in greenhouse gas emission?
- The ice-albedo feedback can substantially contribute to greenhouse gas emission.
- The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions.
- When ice melts, they leave land bare and exposed.
- Melt water collects in pockets.
- Exposed land leads to a decrease in albedo.
- Organisms can thrive more in warm terrain.
- Also, pockets of carbon dioxide gases trapped in ice is released.
- Organisms release carbon dioxide into the atmosphere during cellular respiration.
- Soils originally permafrost will become stable and this will encourage more human occupation of the area.
- All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.

Answer:
Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don't get their sugar from eating food, so they need to make sugar from sunlight. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
