Ecosystems

QuestionAnswer
System A group of parts that work together as a unit.
What are the living parts of a yard system? People, plants and animals.
What two features do open systems have? Inputs and outputs.
Open system The one which interacts with things outside of itself.
Stability Overtime the changes in a system cancel each other out.
Describe two ways in which the parts of a yard system interact. The sprinklers spray water. The sun shines. The grass uses it to grow.
How are inputs and outputs of a system alike? Both are connecting the system to outside.
What patterns show that a yard system is stable? Sunshine - shade, rainy weather - dry weather.
Ecosystem Groups of living things and the environment they live in.
What must a plant or animal be able to do to live in a certain ecosystem? they need to be able to meet their basic needs in it.
Population A group of the same species living in the same place at the same time.
Estuary Body of water which contains more salt than fresh water, but less than ocean water.
How is the mangrove tree different from most other trees? It adapted to live in a salty water.
Community Populations that live in the same area and interact with one another.
In what ways are the living things in a community important to one another? They depend on one another to survive.
What are the main nonliving parts of an ecosystem? Sunlight, soil, air, water, and temperature.
Why do some ecosystems include many living things? Because they have plenty of food, water, and shelter.
Is a row of bean plants in a garden a population or a community? Population. Same species.
What nonliving part of the mangrove swamp limits the kinds of plants that can live there? Salty water
Habitat An environment that meets the needs of an organism.
When might living things have to compete? When their habitats overlap and they either depend on the same kind of food or they might feed on one another.
Niche Role of the population in the habitat.
Food chain The sequence of who eats whom in a biological community.
Three levels of food chain Producers, consumers, and decomposers.
Producers Those who produce their own food: plants, protists, monerans.
Consumers Those who eat other living things for energy.
Decomposers Those who eat the wastes of plants and animals or their remains after they die.
What can happen if too many insect-eating birds live in a habitat? They eat too many insects, then because of the lack of insects some of them either die or fly away. As a result amount of birds come back to normal.
What happens when two similar animals share a habitat? They compete.
What type of organism breaks down the remains of dead plants and animals? Decomposers
How can one organism help control the population of another organism? Insect-eating birds is an example.
Climate Average weather over a long time.
Canopy Roof created by the tall trees in the rain-forest.
Diversity Variety
What makes a tropical rain forest different from any other ecosystem? It has a lot of rainfall and high temperatures all year.
Salinity Amount of salt in water.
How a coral polyp build its skeleton? They build limestone skeletons around their bodies by taking calcium out of sea water.
How are tropical rain forests and coral reefs alike? They provide habitats for a large variety of plants and animals. They both provide resources found nowhere else on Earth.
Where do most plants and animals live in a tropical rain forest? Most of them live high in the canopy of the rain forest.
Why is the salinity of salt water important for a living coral reef? It needs it to grow.
Three resources from tropical rain forests Wood, food, medicine.
