Unit 4 Lesson 1 Flashcards
What makes up an environment ?
Living things and non living things
What are living things ?
Living things are people, plants,and animals.
What are non living things?
Non living things include water, air, soil, and weather
What makes up an ecosystem ?
Living and non living things
Give examples of ecosystems?
Rain forests, deserts, forests, and oceans
How are all parts of an ecosystem connected?
Soil and temperature determine if a plant can grow there
Types of animals in an ecosystem are determined by the plants that are thete
The following are ecosystems Give examples of what makes up each ecosystem Rainforest Coral reef Polar ecosystems Wetlands
Rainforest/trees plants animals weather water and air
Coral reef/ outer skeletons if coal animals fish plants and many type if organisms
Polar ecosystems/ice water organisms that can survive cold, cold and dry
Wetlands/have cypress Teresa with thick trunks to to hold in place
Are organisms evenly distributed amongst ecosystems ? Give example
No they are not evenly distributed
Example /rainforest has more plants polar system has few plants
Give examples of smaller ecosystems that are within large ecosystem
Tree that frog live in-smaller ecosystem
Larger ecosystem Is the rainforest
Corral reef -smaller ecosystem in the larger ecosystem of the ocean
What is a community?
Is made up of all organisms that live in the same place
How do communities change over time ?
Give examples
Natural and human activities change communities over time
Example wild fire
What is a population ?
Group made up of same type of individuals in the same ecosystem
Give an example of population
Antelopes is one population
Elephants another population
Antelopes and elephants can live in the same community
How do populations change?
Due to natural causes
Exsmple -No rain-grasses will not grow-without grass animals do not have food –some animals will not survive
What is a habitat?
A habitat is a physical part of an ecosystem that meets the needs of an organisms
What is a niche ?
A role
A way an organism interacts with the habitat and gets food and shelter are part of its niche
Give examples of different organisms and their niche ?
Duck webbed feet help him swim
Frogs breath through lungs and live at water edge
Give examples of how different organisms compete for resources
They compete when their habitats and niches overlap
Example-tadpoles and mosquito larve compete for algae in pond
Crowded plants at pond compete for sunlight
Do different organisms interact?
Yes
What 3 things do plants use to make food ?
Water air solar energy-(sunlight)
What is a producer ?
A producer is a living thing such as a plant that can make its own food
Give examples of producers
Trees algae and plants
What is a consumer ?
A consumer is a living thing that eats plants or other animals
What happens when consumers compete for food in their habitats ?
When there is too much animals in one place they can die. That’s because there is to much population and they eat the same things
What is a decomposer?
A decomposer is a living thing that breaks down food
Give examples of what provides energy for decomposers?
An overripe fruit a falling leaf or a dying strawberries
What are 2 types of decomposers?
Fungi and bacteria
Give examples if fungi?
Mold mushrooms and yeasts
How do decomposers help the ecosystem ?
They break down food that is dying
Give example of decomposers in our food … That are good
Yeast in bread
Bacteria in yogurt milk or sour crem
How can decomposers help human made pollution ?
They can by breaking down oil spills. Also they add nutrients or oxygen to help decomposers already in their environment
