how do animals meet their needs in an ecosystem

Focus: Students will explore how living things meet their needs for food, water, and shelter. unfamiliar animal to predict how it meets its needs. • describe how living things depend . habitat for the aquatic plants they eat during warm months. Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and An animal may adapt to its habitat in different ways.

Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings. This makes it difficult for predators to seek them out for food. Some animals, like the apple snail, can survive in different ecosystems- from swamps, ditches and ponds to lakes and rivers.

This is often the case in swamps and shallow waters. To know more about how the apple snail can survive in different habitats visit the link. In the harsh cold climate of Alaska, the animals have learnt to adapt to the weather by storing food in their body and protecting themselves from the cold with thick furs.

Plants and Animals in the Environment

Human inhabitants in Alaska have also learnt to cope with the environment by building shelters that insulate and hold the heat, and yet do not allow the structure to melt. To know more about this go to this website. Building a future in which people live in harmony with nature. Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem. Some species are already responding to a warmer climate by moving to cooler locations.

For example, some North American animals and plants are moving farther north or to higher elevations to find suitable places to live. Climate change also alters the life cycles of plants and animals.

For example, as temperatures get warmer, many plants are starting to grow and bloom earlier in the spring and survive longer into the fall. Some animals are waking from hibernation sooner or migrating at different times, too. Disappearing Habitats As the Earth gets warmer, plants and animals that need to live in cold places, like on mountaintops or in the Arctic, might not have a suitable place to live. Learn what you can do to help plants and animals adapt to climate change: Preserve Habitats You can provide wildlife in your very own backyard with food, water, cover, and shelter for raising their young.
