characteristics
Round gobies are small, soft-bodied fish, characterized by a distinctive black spot on the first dorsal fin. Their eyes are large and protrude slightly from the top of the head and, like most gobies, round gobies have pelvic fins which are fused into a single pelvic suction disc on the belly of the fish. Round gobies range in length from 4 to 10 inches (maximum of 9.7 inches
Feeding/Habitat
Round gobies usually feed nocturnally (but have been observed to feed diurnally as well) and are believed to detect prey only while stationary. The primary diet of round gobies includes mollusks, crustaceans, worms, fish eggs, small fish, and insect larvae. Round gobies are native to the Ponto-Caspian region of Europe, but are now considered an invasive species in the North American Great Lakes (where the first round goby was detected, in the St. Clair River, in 1990) and newly colonized regions of Europe such as the Gulf of Gdansk
reproduction
Round gobies exhibit male parental care. Females can spawn up to six times during the spawning season, which spans April to September. Males will migrate from the deeper water, where overwintering occurs, into shallower breeding grounds during the beginning of the mating season. The males are territoral and will guard nests of eggs and newly hatched young, resulting in successful hatch rates of up to 95%. Its eggs are 4 mm by 2.2 mm in size. Female round gobies reach sexual maturity in 1 to 2 years while males do so in 3 to 4 years

some time the heart of the web get exstinked n all hell breaks loose because other species that are need get limited.

the difference between the spring lake and lake michegan was that spring has more species
Spring lake is a more dense lake because it more dirty
The lake that is more clear is lake michegan
Spring lake has more plankton
Lake michegan has a polution problems

video notes
1.) 5 Facts:
- The amount of resources used in making a diaper .
- How much we consume in a lifetime .
- How much of the earth were using .
- That the U.S is the most advanced country .
- How much all together we use in a liftime .
2.) The Law of Conservation of Matter is basically mass of a closed system , That will remain
constant over a long period of time .
3.) Everything were doing is piling up , So all the things we can't get rid of are just sitting somewhere
rotting , Therefore its remaining constant .
4.) The difference between Renewable and Non-Renewable Resources is ,
With a Renewable Resource you can remake or reuse it unlike a Non-Renewable Resource .
5.) Global Warming is the biggest effect on the earth because of things that are produced and can't be reused and or made , So the waste is depleteing the Ovo layer .
6.) America is Wasteful , I feel amercia could do better in conserving things instead of using things
like we have a unlimited amount . Other countries make america look like pigs .
7.)
- Piles of garbage randomly threw out the united states .
- Animals becoming endangered .
- Not being able to thoroughly getting rid of waste .
