What we Want to know

1. The components of ecosystem

2. Different relationships that exit among living things and non-living things

3. Properties and characteristics of different biomes

4. How to converse and preserve our natural resources.

What We Learned

• Biotic

• Abiotic

This consists of life forms existing in a symbiotic relationship with their environment.

Life forms in ecosystems compete with one another to become the most successful at reproducing and surviving in a given niche, or environment.

Biotic – these are the life forms that inhabit in the ecosystem.

Example: producers, consumers, decomposers

Abiotic – these consists of non-organic aspects of the environment

Example: climate, soil, topography

• Predation

• Competition

• Mutualism

• Commensalism

• Parasitism

This is when an organism hunts and eats the other organisms.

The organism hunting is the PREDATOR and the organism being hunt is the PREY.

This is when an organism compete for the same resources.

Insects are common examples of mimicry. Insects can be so blend with their surroundings that sometimes we can not recognize them. Some insects can have the appearance of twigs, leaf, bark, wood and some may simply be the same color as their habitat.

This is the relationship in which organisms benefit from each other.

This is the relationship in which one organism benefits from the other that is not affected.

This is the relationship in which one organism (the parasite) benefits while the other (the host) is harmed.

These are contiguous areas with similar climatic conditions on the earth such as communities of plants, animals and soil organisms.

They are classified in various ways:

Aquatic, deserts, forests, grasslands, tundra

These includes freshwater biomes and marine biomes.

FRESHWATER BIOMES – is characterized by having less salt concentration – usually 1%

MARINE BIOMES – largest biome covering about 70% of the surface of earth.

Characterized by having annual precipitation of less than 25 cm. typical plants that grows are cactus.

Characterized by the presence of dominant plants such as tall, woody and canopy forming trees.

It can be found from the tropical up to the temperate regions.

Characterized by treeless vegetation.

Typical plants that dominates are the grasses and the sunflower family.

Characterized by treeless and has low vegetation with short perennials.

It is also characterized by permafrost, a layer of permanently frozen subsoil.

Two terms that are often confused and used to mean the same thing, although differences exist.

CONSERVATION

• The sustainable use and management of natural resources; including wildlife, water, air and earth deposits.

PRESERVATION

• Attempts to maintain in their present condition, areas of the earth that are so far untouched by human. This is due to the concern that mankind is encroaching onto the environment.

• Biological diversity, or the shorter "biodiversity," (bio-di-ver-si-ty) simply means the diversity, or variety, of plants and animals and other living things in a particular area or region.

• The variety of life in the world or in a particular habitat or ecosystem.

Habitat loss and fragmentation Invasive alien species

Climate change Over exploitation

Pollution Human populations

1. Through a greater awareness, each individual can help to assure that there will be suitable environments for succeeding generations on our planet.

2. Individuals in society must decide on proposals which involve the introduction of new technologies. These decisions must assess environmental risks, costs, benefits, and trade-offs.

3. Act and Be Involved

•Plant a tree.

•Use, reuse or repair things

•Do not use, eat or buy endangered species; e.g. shark fin soup or dumplings

•Support local or sustainable farming (organic farming)

The Sea Shepherd Conservation Society is a non-profit, marine conservation organization based in Friday Harbor on San Juan Island, Washington in the United States. Sea Shepherd uses direct action tactics to protect marine life.

 The World Wildlife Fund goal is "to stop the degradation of the planet’s natural environment and to build a future in which humans live in harmony with nature.“ Their work focuses on the conservation of three biomes that contain most of the world's biodiversity: oceans and coasts, forests, and freshwater ecosystems. Among other issues, it is also concerned with endangered species, pollution and climate change.

The Humane Society of the United States, based in Washington, D.C., is the largest nonprofit organization advocating animal rights in the world.

Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity" and focuses its campaigning on world wide issues such as global warming, deforestation, overfishing, commercial whaling, genetic engineering, and anti-nuclear issues.
