Cycling of Nutrients SNC 1DI

Cycling of Nutrients Except for the few asteroids that arrive on Earth from space, the amount of matter on Earth is always constant All matter is made up of elements in combinations, and since the elements on this planet are not new, they must be recycled This recycling of elements occurs between the biotic factors and the abiotic factors of an ecosystem Sometimes this exchange is quick, and sometimes the elements can be locked into a reservoir for a long time (i.e. glaciers, rocks etc)

The Water Cycle Water evaporates (or is released as water vapour from plants in a process called transpiration) and rises in the atmosphere At a higher, cooler altitude the water vapour condenses into rain/ice/snow and falls to the surface as precipitation Water on land will eventually run-off into streams/ponds/lakes/oceans or seep into the soil to join up with other ground water and/or be taken up by roots of plants

The Water Cycle

The Nitrogen Cycle 79% of our atmosphere is made up of nitrogen gas (N 2 ), however plants and animals cannot use nitrogen in this form Nitrogen fixation is a process that converts unusable nitrogen gas into a useable form, and can occur in two main ways: 1. Lightning – the energy from lightning can convert the nitrogen gas (N 2 ) in the air directly into nitrates (NO 3 ). They then dissolve in rainwater, and are absorbed by plants. 2. Nitrogen-fixing bacteria – found on the nodules of roots of plants and in soil/water. These bacteria convert nitrogen gas into ammonia (NH 3 ). Nitrifying bacteria – take ammonia and turn it into nitrites (NO 2 ) and then nitrates (NO 3 ).

The Nitrogen Cycle Once the nitrates are absorbed by plants, animals eat the plants and eventually change the nitrates into ammonia the waste can be used by bacteria and turned back into nitrates again Other bacteria can turn nitrates back into nitrogen gas, which returns to the atmosphere

The Nitrogen Cycle

The Carbon Cycle most of the carbon on Earth is locked up in reservoirs (i.e. plants, fossil fuels, oceans, animals etc.) the remainder is generally found as molecules of carbon dioxide most carbon is recycled through photosynthesis and cellular respiration

Photosynthesis Occurs in plants (which have a chemical in their leaves called chlorophyll) Chlorophyll captures sunlight and turns nutrients in the plant into stored chemical energy (sugar) the waste product is oxygen gas carbon dioxide + water  sugar + oxygen CO 2 H 2 O C 6 H 12 O 6 O 2

Cellular Respiration occurs in animals and plants to make energy for performing daily functions the waste products are carbon dioxide and water sugar + oxygen  carbon dioxide + water C 6 H 12 O 6 O 2 CO 2 H 2 O

The Carbon Cycle

Producers and Consumers 1. What is the difference between a producer and a consumer? 2. What are the three types of consumers? 3. Distinguish between the following: herbivore, carnivore, omnivore, scavenger, detritivore 4. Explain and give an example of a predator-prey relationship. 5. What are decomposers? Why are they important?
