Answer 1

1. Biotic factors are living factors in the environment: tree, bee, fox. Abiotic factors are nonliving (never-living) factors in the environment: temperature, wind, water.
2. In the ecosystem: ecosystem, community, population, organism (or species). If you mean in one living thing: organism, system, organ, tissue, cell.
3. Niche is the mouse's role in the environment. Mouse eats seeds, other plant matter, and insects. Mouse needs grasses and other material to make its nest. Mouse provides food for its predators: hawks, snakes, foxes, owls. Mouse is home for its parasites: mites, ticks. Mouse may dig tunnels, thus mixing and aerating the soil.
The mouse's habitat depends on where it is. A possible habitat is a farm building like a barn or storage bin. Another possible habitat is a pasture or grassland. Or a deciduous forest.
4. Autotrophs are organisms that make their own food: grass, algae, sunflower.
Heterotrophs are organisms that have to get their food from another organism: mushroom, cat, butterfly.
Carnivores are organisms that feed on other animals: cat, dog, lion.
Scavengers are organisms that find and eat dead things: vulture, crow.
Omnivores are organisms that eat both plant and animal material: people, bears, raccoons.
Decomposers are organisms that break down dead material and absorb the food from them: bacteria, mold.
5. Parasites get food from a host: tapeworm is a parasite in a cow. Parasite benefits and host is harmed.
Commensalism means one organism benefits and the other is not affected one way or the other. Cows move around in the pasture as they feed, and they stir up insects from the grasses. Birds stay around the cows to get the insects as they appear. The birds are helped and the cows are not affected.
Mutualism benefits both organisms in the relationship. Some birds pick out the food that is stuck in an alligator's teeth. The alligator opens wide to get its teeth cleaned. Bird gets food; alligator gets clean teeth. Both are helped.
6. Transpiration is when water vapor goes out of the little pores on leaves. Evaporation is when water vapor goes directly into the air from wherever the water is ... wet soil, stream, wet sidewalk, ...
7. We add carbon dioxide to the air by breathing out and by burning any organic substance like wood, coal, gasoline.
8. A limiting factor is anything that holds down population growth. One limiting factor may be the amount of food that is available. If there isn't as much food available, then not as many in the population can survive.
9. Primary succession is what happens after a major disturbance. There's no soil and no living thing left. So if there was a rockslide and the area is just covered in bare rock, primary succession will begin with lichens. The lichens may be followed by mosses and ferns, then small weeds, bigger weeds, shrubs, shallow-rooted trees, and deep-rooted trees.
Secondary succession is what happens after a more moderate disturbance. There is soil left, so the community doesn't have to start by making soil. The first or pioneer species are likely to be grasses and weeds with lots of seeds, then bigger weeds, shrubs, and so on like the communities in primary succession.
A climax community is the final, stable community that does not undergo further change. In some places the climax community is a hardwood forest. In some places there isn't enough rain to support a forest and the climax community is a grassland. Either way, it's likely to keep the same community over a long period of time without having further changes.

And, as a science teacher myself, my guess is that this is the material that you've been studying for the last two weeks, but you have a set of practice questions for the test.

Answer 2

As a self-taught drummer myself, i can tell you that there really is no 'fast" way to learn an instrument. It takes a lot of patience, practice, discipline, and hard work. Now that being said, some people do learn quicker than others so it all depends on the person. I have two cousins that both play guitar and both are self-taught. My one cousin Terry practiced just about every day and picked it up quicker than my cousin Dave, who didn't practice nearly as much. Terry became pretty darn good in about 8 months. It all boils down to how determined you are, how much you practice, and how quickly you pick things up. My advice would be to get an instructional book or DVD and learn a few chords. If you do it on your own you will save a lot of money and you can go at your own pace. Guitar lessons are not cheap these days, unless you know someone. Just give it a shot on your own for a month or 2 and see how you progress. Then if you feel you need lessons to get better, then find a good teacher that won't be too expensive. But the key is to practice....practice.....practice! Good Luck!

Answer 3

1)Biotic factors= living things in a biom ex= plants
Abiotic= non living things ex= rocks qweather sunlight
2)living things are oraginized in different groups such as tropjhic levels for animals and plantas
3)The niche and habitat for a mouse is most likely to eat insects or seeds and habitat is in the soil or digging tunnels.
5)exp of parasite is the tape worm or musquito.
Commensalism= bird sitting on a cow or a hoarse
mutualism=bee on a flower
7)drive cars, or buring natural resourcer or fossil fuels
8)somthing that limits the growth of a population

Answer 4

#7 is breathing...other than that, you're on your own. Your teacher is mean!
