chapter 3

MAIN POINTS

Soil – Vegetation can help us keep soil healthy and in place.

Ecosystems – It affects the animals and other living things in many different ways.

Climate – Plants can help control the climate by affecting temperature and rainfall.

People – Vegetation affects how people live, including whether they have enough food, water, and resources.

They can have less precipitation than trees.

They can survive in drier regions.

They include species like wildflowers and other grass-like plants, such as sedges and rushes.

Many animals' home

Tropical grassland (Tanzania, Africa) and mid-latitude grassland (Argentina, South America) are the two types of grasslands.

Tropical broadleaf forests (eg. Thailand, Asia)

Subtropical broadleaf forests (eg. Mexico, North America)

Mediterranean forests (Italy, Europe)

Broadleaf deciduous forests (Canada, North America)

Mixed forests (Japan, Asia)

Needleleaf evergreen or boreal forests (Finland, Europe)

Deserts

Grasslands

Forests

Each of these regions covers about one-third (1/3) of the Earth’s land area.

They're plants that grow by itself, unlike those planted by people.

Trees grow from below sea level to high mountains

Boreal forests are in the north, tropical forests grow between the tropics, and subtropical forests are just outside the tropics.

Some trees need a lot of water, while others need very little.

Trees can either be coniferous (needle shaped leaves) or deciduous (lose their leaves). Broadleaf trees have broad, flat leaves. Some lose them (like maple and oak), and some stay green all year.

They have extreme high temperature

It has about 250mm or less of precipitation per year.

The amount of rain affects how quickly it evaporates.

Semi-desert scrub-hot regions (Bolivia, South America), Desert-hot regions (Morocco, Africa), and Tundra and High Mountain vegetation-cold regions (United States, North America)
opic are the three types of desserts.

Many plants use energy from the sun to make CO2 from the air and water. After that, oxygen and carbohydrates are created

They can provides animals with natural habitats

People use materials from plants to build shelters, furniture, and modes of transportation, a way to make resources.

Camping in forests, hiking or skiing on mountain trails and boating or swimming/ecotourism, are all the types of recreation.

Indigenous people can strongly connect to the land -this is called spiritual connection
