What causes the moon's phases?

The changing angles at which we see the illuminated portion of the moon as it orbits Earth

Q: The Universe is made up of

A: Galaxies

  • Decomposers: 




Organisms that break down dead organic matter, releasing nutrients back into the ecosystem.

100

  • Pollution:
Air, water, and soil pollution can harm living organisms and disrupt ecosystem processes.

  • What is a mechanical wave? 




A wave that requires a medium (like water or air) to travel.

The Moon goes through 8 distinct phases as it orbits Earth, caused by the changing angles at which we see the sunlit portion of the Moon.

These phases are: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. The entire

  • Consumers




Organisms that eat other organisms for energy.

Deforestation

Clearing forests for agriculture or urbanization can disrupt ecosystems and reduce biodiversity.

What is a transverse wave?

 a wave where the particles of the medium move at a 90-degree angle to the direction the wave travels

300

During which moon phase do spring tides occur?

 new moon and full moon

plants orbit

stars

  • Producers: 


Organisms, like plants, that make their own food using sunlight (photosynthesis).

  • Climate Change:.
Shifts in temperature and precipitation patterns can impact species distributions and community structure.

What is a longitude wave?

  Longitudinal waves cause the medium to move parallel to the direction of the wave.

what effects does the tilt of the earth's Rotation access have on the seasons

 changing temperatures and daylight hours as the seasons progress

What is a spiral galaxy?

A:with spiral arms that curve out from a region

  • What isEnergy: 


The ability to do work, and in ecosystems, it usually refers to the sun's energy.

What are some examples of natural changes in ecosystems?


  • Succession:.
 plants grow and mature, they can create conditions that favor other species, leading to a gradual change in the plant community.

 What is a Wavelength

Wavelength: The distance between two successive crests or troughs of a wave

Ecosystem dynamics involves

studying how ecosystems change over time due to natural processes and human activities.
