Plant Parts, Life Cycles and Uses
This part of the plant makes food/energy for the plant using sunlight.
The leaf
This plant part absorbs water and nutrients from the soil.
The root
A habitat is a place that provides living things with these four basic needs. Name two.
Food, water, shelter, space
What does a herbivore eat?
One example of a positive impact humans have on the environment
ex: planting trees
This plant part helps the plant reproduce and make seeds.
The flower
Plants use sunlight to make their own food through this process.
photosynthesis
A community is made up of this.
Different species living and interacting in the same habitat
Organisms that break down dead plants and animals are called this.
Decomposers
One example of a negative impact humans have on the environment.
ex: cutting down forests
Put these in order: seed, adult plant, seedling, germination
seed → germination → seedling → adult plant
Name two things plants need to survive.
water, sunlight, air (carbon dioxide), nutrients, heat, space
If a species becomes extinct, this can happen to the food chain.
It becomes unbalanced / other species may decline or increase
Explain the difference between a food chain and a food web.
A food chain is one path of energy; a food web shows many connected food chains.
Name one benefit of locally grown food.
less transportation, fresher food, supports local farmers
Name two ways people use plants.
food, medicine, clothing, shelter, tools
During photosynthesis, plants take in this gas and release this gas.
carbon dioxide in and oxygen out
Name one factor that can affect whether a community survives in a habitat.
Food supply, water availability, climate, space, predators, pollution, human activity
Why do habitats have limits to how many plants and animals they can support?
Limited food, water, shelter, and space
Name two actions people can take to prevent species from becoming endangered.
Protect habitats, reduce pollution, recycle, plant native species, reduce waste, conserve water, create protected areas
