Study Notes
Life Cycles
- Organisms go through observable changes during their life cycles, including birth, growth, development, reproduction, and death.
- A life cycle is the particular way a living thing grows, reproduces, and dies.
- A stage is a single step in a process.
Stages of Insect Life Cycle
- Egg (unborn stage)
- Larva (the young stage when most feeding is done and the insects look like worms)
- Pupa (the no-feeding stage when the insect is camouflaged inside a sac and changes from a worm shape to a full-grown insect)
- Adult (the stage when the insect leaves the pupa, usually has wings, and is ready for reproduction)
Adaptations and Environments
- Structures of plants and animals are adapted to particular environments.
- Examples of adaptations:
- Blubber of seals to survive in cold weather
- Fur of rabbits to survive in cold weather
- Waxy coating of a cactus to survive in hot, dry conditions
- Presence of spines instead of leaves to survive in hot, dry conditions
- Polar bear adaptations:
- White fur to blend in with the snow
- Layer of blubber to stay warm
- Sharp claws to catch prey
- Hibernation since food is scarce in winter
Environments
Grassland
- A place made up of large open areas of grasses
- Maintained by grazing animals and frequent fires
- Trees can be present, but often are not
- It does not rain often
Tundra
- A place found in the Arctic and on the tops of mountains
- Climate is cold and windy, with scant rainfall
- Land is covered with snow for much of the year
- Typically treeless regions
Tropical Rainforest
- A hot, moist environment with high rainfall throughout the year
- Dense canopies of vegetation with three different layers (canopy, understory, forest floor)
- Plants on the forest floor adapt to survive with little sunlight
Ocean
- Areas of salty water that fill enormous areas on the Earth's surface
- Divided into five different sections (Pacific, Atlantic, Indian, Southern, and Arctic Oceans)
Wetland
- A place where the land is covered by water—salt, fresh, or somewhere in between—either seasonally or permanently
- Vegetation (plants) can often be found in a wetland
Desert
- Areas that receive very little precipitation (rainfall)
- Often very hot, so many animals are active at night when it is cooler
