Answer the following questions with a picture only PLEASEEEEE.
1. What is the main source of energy for ecosystems?
2. What are some natural things that can disturb ecosystems?
Answer:
1.Photosynthesis is the process of converting light into energy
2.Natural events, such as wind, drought, flood, fire, or disease.
Explanation:
1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.
2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

A student uses a lever and fulcrum to lift a rock off the ground.
Which option describes when potential energy is converted into kinetic energy during this process?
a. when the lever is wedged beneath the rock but before it has been lifted
b. when the student presses down on one side of the lever to cause it to move
c. when the rock rests on the ground without the lever
d. when the rock rests above the ground
Answer:B
Explanation: I know this because kinetic energy is when something is moving and potential energy is when something is not moving and the energy is being stored so it has you are pushing on the other side moving the object it is transforming the potential energy also known as stored energy into movement also known as kinetic energy

Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the low pressure system to the high pressure system, causing wind. The wind will carry moisture since it is coming from the ocean. Choose the statement which corrects the error(s) in Jennifer's prediction.
a weather map of Florida with an L to the left of Florida over the ocean and an H over the land
a The wind from the ocean will not carry moisture.
b The wind will travel from the high pressure system to the low pressure system.
c Since the low pressure system is not over land, wind will not be created.
d Wind is only created when two high pressure systems meet.
Answer:
b The wind will travel from the high pressure system to the low pressure system.

Answer:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!
Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.

Explanation:
The local newspaper has published the passage below.
Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.
Which statement in the news passage above is inaccurate?
The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.
Solar winds do not reach well beyond our planet.
Answer:
Solar winds do not reach well beyond our planet
Explanation:
I hope this helps :)
Solar winds do not reach well beyond our planet.because Traces of solar wind reach well beyond Earth and have been detected as far as Saturn. says that

--------------im just trying to fill space for the minimum 20 char
The answer is probably tt
Well for parent 1 and parent 2 ( 1st parent of 2 ), parent 1 shows T so it forms Tt
Parent 1 and 2 ( 2nd parent of 2 ) ( parent 1 also has T and parent 2 has t ) so it forms Tt
Parent 1 ( 2nd parent of 1 ) and parent 2 has t and parent 1 is normal which forms tt
So that leaves 2nd parent 1 and parent 2

all I need you to do its to type out these pictures word for word it pretty simple
Answer:
Disease can reduce the size of a population quickly.
The amount of resources, such as food and water, limit how many pikas can survive.
The presence of predators limits how large the population can grow.
As the population grows, the pikas compete with each other for resources.
The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.
