Glossary

Population - A community/particular group of the same species which are living together in the same place at the same time.

These are a population of deers that are moving as a group which are at the same time and place.

Communities - A group of populations interacting and living with each other in an area.

This is a community of zebras and giraffes in an area at Africa.

Habitats - The natural home or environment where a specie normally lives in. (The location of a living organism)

These are habitats of different areas of the world where various species live.

Ecosystems - A community and its abiotic environment.

This is an image of two otters hiding in a ditch.

Species - A group of organisms that can interbreed to produce fertile offspring.

These are wolves of a certain species which means they can interbreed.

Biodiversity - The variety of organisms in the world or in a particular habitat.

This is a diversity of animals of different species

Abiotic Factor - A non-living organism such as a habitat or climate which affects an ecosystem or the organisms living in it.

Soil is one of the various abiotic factors that can affect an ecosystem or living organisms.

Biotic Factors - A living organism that affects the ecosystem or other living organisms living in it.

Jellyfish is one of the many other biotic factors that is able to affect the ecosystem as well as the organisms living in it.

Niche - A term for the role and position for the species such as how it survives and reproduce.

Sustainable - The development that fulfil the needs of the present without compromising the ability of the future generations to meet their needs.

Producer - Plants are called producers. It is because they produce their own food by photosynthesis.

Consumer - Animals are called consumers. This is because they cannot produce their own food, so they need to consume other plants and/or animals.

Primary Consumer - Primary consumers are usually herbivores and fungus.

Secondary Consumer - Secondary consumers are mainly carnivores and prey on other animals.

Decomposer - Bacteria and fungi are decomposers. They eat decaying matter, dead plants and animals. In the process, they break them down and decompose them. It gives nutrients to the soil.

Food chain - It is a series of organisms that rely on each other to feed on each other.

It starts of with a plant which is the producer to the primary consumer then there is the secondary consumers which continues until the last consumer dies which is the fox in this food chain.

Prey - An animal that is hunted and killed by another for food.

Predators - An animal who naturally preys on other animals.

Carnivore - An animal who feeds on other animals

Herbivore - An animal who feeds on plants

Alkali/Acidic Soil Practical
These were the steps that we took to test the PH of the soil for test C which was Ph10.
This was test B which we filtered that ended up with Ph1
Lastly, we did test A that was filtered with Ph4 which is the yellow
The first filtered in the picture is test A then test C then B.
This is an evergreen shrub which has adapted to live in the alkaline soil.
Sweet potatoes are a vegetable that requires acidity to survive.

What is a wetland?

A wetland is a land consisting of marshes or swamps; saturated land.

Where are they located?

The Pantanal located in Brazil, Bolivia and Paraguay

The Camargue in France.

Wasur National Park in Indonesia

Kakadu Wetlands, Australia.

Kerala Backwaters, India

Wetland Park Rd, Tin Shui Wai, Hong Kong.

Hong Kong Wetland Park.

Why are wetlands important?

The wetlands are important because they are a crucial part in the natural environment. They protect our shores from wave action, reduce the impact of floods, absorbs pollutants and improve water quality. Not only do they provide habitats for animals and plants that contain a wide diversity of life but also supporting the plants and animals that can be found now where else. They also provide nurseries for fishes and other freshwater and marine life.

What is a mangrove?

It can be referred as two things: a tidal swamp ecosystem that is found in tropical deltas, estuaries, lagoons or islands and the tree species populating this ecosystem. Mangrove trees have adapted uniquely to the harsh conditions in the natural environment. An example of one, is its roots adapt to the shorelines so it has more stability living there. Another adaption is to the tolerance of salt where when there is less salt it turns red while black and white mangroves are for when there is more salt.
