Species adaptions provide them with survival advantages in a particular environment

A fact o About adaption is

Everyone's responsibility

Aquatic resource conservation is

Plastics work dipped in stinkbait

Best bait to catch a channel catfish

Live minnow

Best bait to catch a large mouth bass

Below a riffle in weeds near a stream bank

Best habitat for a Bluegill

Open water zone of lake

Best habitat for a largemouth bass

While living organisms have the caps to produce populations of infinite size environments are resources are limited

Carrying capacity is the result of which of the following

Every Time water evaporates it becomes pure again

How does the water cycle purify water

Cloudy water blocks light and slows plant growth To much fertilizer causes overgrowth of algae Toxic chemicals are poisonous to living things

How does water pollution affect aquatic life

Cold water hold more oxygen

How does waters temperatures affect the amount of oxygen in it

Include tiny free floating species of algae are food base of ecosystems Have waxy of slimy coatings protect them from drying out when water levels drop and proud stems or leaves let them absorb minerals right from the water

Plants living in lakes and ponds

Some fish plants or other aquatic life could be washed downstream There would be no long term damage Fresh nutrients would be brought in

Predict the impact of flossing on the organisms in a stream ecosystem

Pond succession would speed up

Predict the impact of sediment and nutrients brought in by storm water runoff on the organisms in a lake

Oxygen levels are high each day while the sun is shining and plants are photosynthesizing but they can drop dramatically at night

Predict the oxygen level in a pond

Saturated soil wet for major part of growing season plants plants specially adapted to live in saturated soil

What are three factors are required for a place to be considered a wetland

A type of plant or animal no longer in existence having died out leaving no living representatives

What does it mean for a species to be extinct

Careful use

What is Conservation

Animals with a backbone A particular kind of creature

What is a species

Exhibits surface tension Acts as a solvent Is transparent

What is a unique substance. It can be found in all three states on earth -solid liquid gas which are the following are other properties of water

All the land that drains water into a particular body of water

What is a watershed

A type of plant or animal whose numbers are so small that is at rush of extinction

What is an endangered species

The variety and number of different organisms and populations and the way they live together

What is biodiversity

Average atmospheric conditions in an area over many years

What is climate

Dead plants and animal matter in the process of decay

What is detritus

Water pollution from many different sources

What is non point pollution

Pollution that comes from one single source

What is point pollution

Any bit of rock or soul that is suspended or carried in water

What is sediment

Human caused habitat destruction

What is the biggest threat to aquatic communities

All water on earth

What is the hydrosphere

The invasive species may compete with the native species for habitat or food

What is true about invasive species

In a straight stretch of river the main force of the current is in the middle the deepest water is all in the middle When there is there a sharp bend in the river the strongest current and the deepest water is at the outside edge of the bend In flowing water the is less current near the bottom

What is true about streams

The movement of water through the water cycle

What is weather

Rivers lakes and wetlands

What kinds of aquatic ecosystems do we have in missouri

3 percent

What proportion of the water on earth is fresh water

To drinking water treatment plants then through pipes to our taps

Where does water go when it goes down the drain

A population within a community may compete with other populations within the community Individual within a population may compete with other individuals of the same species Individuals within a population may compete with individuals of different species

Which of the following statements about competition is true

Reeds and other grasslike plants grow in marshes while woody species trees and shrubs thrive in swamps

Which of these statements are true about Missouri wetlands

Most of the a available food energy is lost moving up each tropic level Animals loose energy doing tasks such as jj run and keeping their bodies warm Only a little of the sun's energy passes from one tropic level to the next

Why can most energy pyramid continue for only 4 or 5 tropic levels and support only a few top level consumers

To estimate things without having to count each organism

Why do scientists use sampling
