Omar often saw woodpeckers perched in trees in his backyard, but he never saw them at his bird feeders. Omar usually filled his feeders with sunflower seeds. He wondered if he could attract woodpeckers by adding a different type of food to the feeders.
To test this idea, Omar gathered eight identical bird feeders. He filled four with sunflower seeds. He filled the remaining four feeders with crushed peanuts. Omar then placed the bird feeders in his backyard. Over the next five days, he counted the number of woodpeckers that visited each bird feeder each morning.
Which of the following was an independent variable in this experiment?
Answer: The food
Explanation: the independent variable is the one to be changed and in this case, it is the food
When do the finches on the Galápagos Islands learn their songs? From whom do they learn their song?
Answer:
Like children learning to speak, little finches learn songs from their elders. ... They let the animals peck at a key, which caused a plastic father finch to "sing" them a recorded song, up to 28 seconds per day. The scientists then measured how the youngsters slowly approached perfect imitation.

D. Shivering and thirst.
Answer:
Sweating and thirst, I think!
Explanation:
When you are too hot, your body will sweat to cool you down. There will be less water in your body because the heat will dry it and you will be sweating, so you'll be thirsty.
It has often been said that the next dominant animals on land, after a hypothetical demise of all mammals, would be the insects. Why so?
Explanation:
The animals that dominate the Earth today are the human species or Homo sapiens. Many factors have allowed the species to dominate the Earth-like use of new tools, vocal cords, and an increased sense of intellect and natural intelligence. But today we can observe the social wars, epidemic, and harm to our planet which could result in the extinction of humans.
The scientist has hypothesized that after the Homo sapiens, new dominating species will be insects as this group of the organism has:
1. Survived many mass extinctions.
2. are highly adaptable to extreme conditions.
3. Has evolved many adaptive features to protect itself from prey like a tough exoskeleton, few to many legs, bombarding in few species when someone tries to eat it, and many others.
Which term is correct for one female arctic fox? biome species ecosystem organism
Answer:

So if the Moon's shadow is falling on the Earth during a solar eclipse, what phase of the moon must it be? (The moon is between the Earth and Sun.)
Answer:
New moon
Explanation:
A solar eclipse can only occur during New Moon (when the entire moon is covered in darkness and not visible from the earth's surface.) A total solar eclipse can be seen within the moon's dark inner shadow (called the umbra.) A partial solar eclipse can be observed within the earth's lighter outer shadow (called the penumbra).

Why does the presence of predators help keep an ecosystem stable?
A. The predators eat the keystone species.
B. The predators keep prey populations balanced.
C. The predators decrease biodiversity
D. The predators stop species from competing,
Answer: B
Explanation:
The predators keep prey populations balanced. Therefore, option (B) is correct.
What are predators?The presence of predators in an ecosystem helps to keep the population of prey species balanced. If the predators were absent, the prey populations could grow unchecked, leading to overconsumption of resources and potentially damaging effects on the ecosystem.
By keeping the prey populations in check, the predators help to prevent such imbalances, contributing to the overall stability and health of the ecosystem.
Predators also tend to prey on the weaker and less fit members of a population, which in turn helps to strengthen the gene pool of the prey species over time. This balance of predator and prey populations is an essential component of a healthy and stable ecosystem.

Someone help with me this :/
1.) How does the arrangement of who eats whom compare with the arrangement of the number of individuals?
2.) What might happen to the other organisms if algae were removed from this group? What might happen if killer whales were removed?
3.) Are there any organisms in this group that eat more than on kind of food? How would you change the order of your cards to reflect this information?
If it's a good answer I'll mark brainliest
Answer:
1. The energy flow to the blue whale would be from the algae and the krill
2. If the killer whale where to be removed from the ecosystem the rest of the ecosystem would increase and wouldn't have a predator to dial down the populations so it would spiral out of control
3. if the algae population increased then the the rest of the ecosystem would increase
4. the fish population would grow and the organisms that the fish feed off of would decrease leaving the rest of the ecosystem to decrease because they would need the krill and algae

What are greenhouse gasses? How does carbon dioxide enter the atmosphere? (Site 1)
Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
Answer:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.
