What makes up an ecosystem? What are the four ecosystems we learned about?

Living things and their nonliving environmentEcosystems: pond, desert, rain forest, and coral reef

Ecosystems - $100

Give two examples of biotic and abiotic factors.

1. Biotic: Plants, animals, and microorganisms.

2. Abiotic: Rainfall and temperature.

How do desert animals survive very hot and cold weather? How do they

get their water?

They live underground

They get their water from the food they eat.

Ecosystems - $300

Name one abiotic factors in a pond ecosystem.

Name one abiotic in coral reef environment.

Pond ecosystem: water, soil

Coral Reef ecosystem: Coral

Ecosystems - $400

Emergent layer – the tops of the tallest trees

Canopy layer – has snakes and treefrogs

Understory layer - below the canopy layer

Forest floor - very few plants grow here because there is little light.

Name and describe the four layers of the rain

forest.

Ecosystems - $500

How are plants used as shelter?

Birds use plants to build their nests that they use as homes.

Plants (e.g., trees) give animal a place to hide and

stay safe from harm.

Dependence on Each Other - $100

How do animals help the process of pollination?

Animals travel from flower to flower and the pollen sticks to them. When they go to a new

flower they rub the pollen on it and it helps it reproduce.

Dependence on Each Other - $200

How do plants depend on animals to carry seed?

Animals eat fruit and leave fruit seeds on the ground in their waste. Some seeds stick to animals’ fur and fall to the ground and grow into new

plants.

Dependence on Each Other - $300

How do animals depend on plants?

• Plants produce oxygen. • Plants are eaten by producers who

would not survive without them. • Plants that are no longer living are

eaten by decomposers. • Plants are the main source of energy

entering food chains.

Dependence on Each Other - $400

What is the process called when male cells (stamen) are transported

to female cells (pistil) in a flower? The ovary at the base of the pistil turns into what after pollination?

Pollination

Fruit

How can a fire help an ecosystem?

An individual organism’s response to change is called

What happens when ecosystems change?

Animals change their behavior and habits to survive changes in the

ecosystem.

•What does endangered mean?

•What does extinct mean?

• Endangered means there are only a few of a specific plant or animal alive in an ecosystem.

• Extinct means that the specific animal or plant has all been destroyed or died.

What do adaptations help an animal do?

Adaptations help animals move, catch food, and live

in certain climates.

Adaptations - $100

What are some adaptations of ocean animals?

• Some animals have blubber to keep their body warm in the cold ocean water.

• Some animals confuse its predators by looking like something else.

Adaptations - $200

What are some adaptations of desert plants and animals?

• Plants have adapted so they need little water.

• Some animals live underground to keep cool and safe.

• Some animals sleep during the day and are active at night (nocturnal) when it is cool.

Adaptations - $300

DAILY DAILY DOUBLEDOUBLE

What are adaptations and give two examples of them?

Adaptations are special features that help living things survive in their

environment. A fish’s gills , a dragonfly’s wings, and an eagle’s sharp eyesight are adaptations.

Adaptations - $400

How do animals adapt?

Some animals use camouflage to blend into their environment. Other animals use mimicry to

hide by looking like other organisms.

Adaptations - $500

• It is a sweet drink found inside a flower.

• It is the study of how organisms pass traits from one generation to the next.

What are some adaptations of arctic plants and animals?

Potpourri - $400

Animals have special adaptations to help them survive the cold. Polar bears have inner fur to keep it warm and outer fur to keep it dry. Some animals have large bodies so they don’t lose as much body heat.

What does pollution do?

Make living things sick and can even raise the

temperatures on Earth.

Science

• Natural events such as changes in weather and climate (e.g., hurricanes, tropical storms, drought) can cause ecosystems to change. Human activities such as air pollution, cutting down forests and digging for resources in Earth’s surface can cause ecosystems to change.

• Laws are made to limit pollution and make hunting certain animals or picking certain plants illegal.

What causes ecosystems to change? How can people protect ecosystems?
