Biomes are living components such as land and animals.Biomes are the largest divisions of the biosphere, the large regions within biomes have similar biotic and abiotic components.The interactions of components tells you how biomes will act.temperature along with percipitation are main abiotic factor that helps to determine the distribution of biomes and organisms inside them.Biomes contain large regions that have very similar biotic components like plants and animals also similar abiotic components like temperature and amount of rainfall.
Biotic components - Living organisms , plants and animals , fungi and bacteria
Abiotic components - Non living chemical and physical parts of enviroment , light , radiation , temperature , water and soil.

Different Biomes
- Aquatic
- Boreal forest
- Grassland
- Desert
- Permanent ice
- Temperate deciduous forest
- Temperate rain forest
- Tropical rain forest
- Tundra

1.2 Ecosystems
Ecosystems - An ecosystem is a natural area in a enviroment where physical meets compatible as (abiotic) factors such as rocks and soil works togather with (biotic) organisms such as plants and animals well in the same habitat to maintain a stable ecosystem.
The ecosystem is a stable set of relationships among living an non living organisms habitats an residents of an area.Which includes plants , trees , animals, fish , birds , micro organisms , water , soil , and us the people.These ecosystems are very large in size an the elements in it, but each works as a functioning unit.Everything that lives in the ecosystem depends on other species and elements who also make up the functioning community and if one part of the the system is damaged everything is impacted. When its a healthy ecosystem it is sustainable.

2.1Ecosystems Energy Flow

Food Chains - shows relationship between varieties of living things in a particular environment or habitat.
Food Web - like food cycle series of organisms related by predator-prey and consumer-resource interactions.
Tropic level - Of a organism is the position it takes up in a food chain.

2.2 Nutrient Cycles In Ecosystems

In this section, you look at the three important nutrient cycles that move these nutrients through terrestrial and aquatic ecosystems.

Nutrients - Is what an organism needs to live and grow.
Nutrients cycles - Cycles through ecosystems by photosynthesis, cellular respiration and decomposition.
Nitrogen cycle - The nutrient cycle in which nitrogen is moved through biosphere.
Carbon cycle - Cycle in which carbon is moved through the biosphere.
Phosphorus cycle - The nutrient cycle in which phosphorus is moved through biosphere.

2.3 Effects of Bioaccumulation on Ecosystems

Bioaccumulation - The gradual build - up of synthetic and organic chemicals in living organism.
Biomagnification - Toxic chemicals and heavy metals flow into the ocean when industrial, agricultural, and human wastes runs off concede discharged into rivers that then empty into the sea. Pollutants cause disease, genetic mutations, birth defects, reproductive problems, behavioral changes, and death in many marine organisms.Difficulty of damage varies greatly between species. In many cases, animals near the top of the food chain are most affected because of a process called biomagnification.

Ecosystems are places that naturally change over time. Biodiversity includes both number of species and overflowing quantity relative to each other. The changes in an ecosystem that typically cause concern are the large, drastic ones that reduce biodiversity down to only a few highly dominant species.In natural selection, the best-adapted members of species will survive and reproduce.Many changes occur in ecosystems. Ecological succession refers to changes that take place over a period of time in the types of organisms inhabiting an area.
Two types of ecological succession : Primary succession and Secondary succession

Primary succession - The development of new life in areas where no organisms or soil previously existed, such as on bare rock.
Secondary succession - The reintroduction of life after a disturbance to an area that already has soil and was once the home of living organisms.

Humans everywhere have affected natural ecosystems. These activities have become increasingly apparent; a time to take action is required. The new generation will feel the consequences more strongly than anyone before. Our understanding and involvement is essential from the outset because the repercussions, though not only our fault, will most certainly be our problem. Environmental problems are easily observable and are soon no longer becoming resolvable. Humans altering natural ecosystems, which then affect other ecosystems around the world, in general, cause the problems. We need to educate the children about this issue by showing them what brings negativity to the ecosystems like when you drop litter, drive cars, farm intensively.
Pollution is contamination by poisonous or harmful substances. Smoke or harmful gases, from factories, can pollute air and mainly car exhausts. Water can become polluted by dumping of waste from household things and factories at sea or in rivers, and by the spread of chemicals used on farms, pesticides and chemical fertilizers.
Water as well as air pollution spreads far from its source, harming ecosystems in other areas. When one ecosystem is damaged it cannot interact with others.
If the first ecosystem is destroyed, then it cant form clouds, giving off less rain to the second ecosystem. All the organisms in the second ecosystem will be affected. That will transfer to further ecosystems.
invaded ecosystems may lack the natural competitors and predators that keep introduced species.

How climate can be influenced by human activities? Litter can harm the environment in a number of different ways. It is a breeding ground for disease causeing rodents and damages the appearance of the enviroment.Open containers such as paper cups or beverage cans can hold rainwater cause diseases like Malaria.Uncollected litter can flow into streams and rivers. Infacted About 18% of litter, usually traveling through storm water systems, ends up in local streams, and rivers. And what about the animals, Animals may get trapped or poisoned with litter in their habitats.Cigarette butts are a threat to wildlife and have actually been found in the stomachs of fish, birds amd whales that have mistaken these items for food. Garbage falling from vehicles is increasing automobile accidents.It often takes a long period of time to get rid of.

    Human activities create climate change by changes in the earths atmosphere and the amount of greenhouse gases. Have you ever tried recycling? Well I have I learnt that in the city of Kingston collects recyclable material in a two-box system that involves the use of separate Grey and Blue boxes on alternate weeks. Please place your blue box or grey box at the curb by 6 a.m. on your scheduled collection day. By collecting recyclable in this fashion the City has reduced collection costs by 20 per cent a net savings of $1.1 million from July 2006 to July 2012. This is all because garbage men don't have to spend as much time sorting recyclables at the foot of each driveway resulting in more stops per day.


Grey Boxes - are for paper products and plastic bags. Newspapers, milk cartons, cereal boxes flattened.
Blue Boxes - are for the rest of your recyclables including metal food and beverage cans, rigid and foam plastic containers. Also standard sized boxes help keep recycling loads manageable to prevent worker injury. But not only are there blue and grey boxes in Kingston Ontario but also here in surrey BC many places are catching on and preventing climate change
