Question

Explain how human activities are changing the carbon cycle, and describe biological responses to those changes such as changes in phenology.

Answer 1

Nowadays due to the industrialization in wrong ways without proper measures to reduce environmental pollution,

a huge amount of greenhouse gases are emitting. the wrong method of recycling or treatment of waste materials can cause serious harmful effects to the plants and animals

Following activities can change the carbon cycle

1. Burning of fossil fuels.

when burning fossil fuels a huge amount of co2 and other toxic greenhouse gases are emitting.

2.cuttng of trees

Pants using co2 for photosynthesis.decrease in photosynthesis increase levels of co2.

3. Emitting of co2 from factories

Factories usually emit a huge amount of greenhouse gases including co2

  

All the above mentioned human activities can increase the carbon dioxide amount.plants are the key factors that reduce the co2 and increase the amount of oxygen. due to deforestation their number s decreasing nowadays.

How increases in co2 affect earth balance?

increase in co2 in the atmosphere can trap the heat of sunlight. these results in the temperature of air, land, and water.

There is an optimum temperature for every enzyme and proteins to work actively. beyond the optimum temperature denaturation of these proteins and enzymes which means the entre metabolic activities in organisms become damaged.

In plants, minute temperature differences can affect their growth and production which means since plants are the primary producers reduction in their productivity entirely affect all consumers.

many organisms show migratory behavior during different seasons. Changes in the temperature and thereby changes in the seasons can affect these kinds of organisms In a bad manner.

CONCLUSION

Hence increases in the amount of carbon dioxide like greenhouse gases can entirely affect the life on earth Iincludng changes in the seasons, rising temperature in the land, air and water , changes in the optimum temperature of body enzymes, proteins, and other biomolecules, affect the seasonal migratory organisms, growth and development of plants and their production.
