Which of the following biogeochemical cycles can be influenced by human activity and cause eutrophication of a local water supply?
Question 1 options:

oxygen cycle

water cycle

nitrogen cycle

carbon cycle

Question 2 (20 points) Question 2 Unsaved

The burning of fossil fuels releases which of the following gases into the atmosphere?
Question 2 options:

carbon dioxide

nitrate

nitrogen

oxygen
Question 3 (20 points) Question 3 Unsaved

Carbon dioxide enters the atmosphere through each of the following processes except one. Which one?
Question 3 options:

respiration

photosynthesis

burning fossil fuels

volcanic eruptions
Question 4 (20 points) Question 4 Unsaved

Carbon in the bodies of marine organisms is often found in which of the following forms?

Question 4 options:

clastic sedimentary rock

chemical sedimentary rock

igneous rock

layered sedimentary rock
Question 5 (20 points) Question 5 Unsaved

The carbon cycle works in conjunction with which of the following?
Question 5 options:

cycling of oxygen

all biogeochemical cycles

water cycle

nitrogen cycle
WILL MARK MOST BRAINLIEST!!!!!

Atmospheric sources of nitrogen contribute to Eutrophication. Fossil fuels and fertilizers release nitrogen into the atmosphere. Excess nitrogen increases the fertility of marine ecosystem and results in Algal Bloom, hence the balance is disturbed.

2- Carbon Dioxide

Fossil fuels produce huge amount of carbon dioxide on burning. Carbon emissions form a layer of blanket and eventually trap heat in the atmosphere which leads to climate change.

3- Photosynthesis

This process makes use of the CO2 already available and the end products are glucose and oxygen.

4- Chemical sedimentary rock

Like Limestone which is used in concrete and building materials.

5- All biogeochemical cycles
