AQUATIC ECOSYSTEM
Name the three types of aquatic ecosystems.
FRESHWATER - MARINE ECOSYSTEM - ESTUARY
Mention the adaptation that organisms have to survive in a FAST-MOVING AREA
Organisms that live in fast-moving water are adapted to resist being washed away.
WHAT IS MATTER?
anything that has mass and takes up space.
MENTION 2 HUMAN ACTIVITIES THAT CONTAMINATE
OPEN QUESTION
The process by which plants make their own food using the sun's energy IS......
PHOTOSYNTHESIS
Name four major abiotic factors that affect aquatic ecosystems.
ANY OF THESE:
TEMPERATURE, DEPTH, AMOUNT OF LIGHT, OXYGEN LEVELS, PH, SALINITY, RATE OF WATER FLOW.
A partially enclosed body of water formed when a river flows into an ocean is
ESTUARY OR WETLAND?
ESTUARY
WHAT IS ENERGY?
the ability to do work in general for example running or jumping.
DESCRIBE HOW Factories and automobiles DAMAGE THE ENVIRONMENT
burns fossil fuels that release harmful chemicals into the environment.
WHAT IS THE ATMOSPHERE?
A mixture of gases that surrounds Earth.
WHAT TYPE OF AQUATIC ECOSYSTEM WE CAN FIND IN THE FOLLOWING PLACES:
LAKES, PONDS, WETLANDS, RIVERS AND STREAMS.
FRESHWATER
Mention 3 examples of marine ecosystems.
Open ocean
Coastal ocean
Deep Ocean
HOW PRODUCER GET ENERGY?
Producers get energy from the sun, especially when making their own food through photosynthesis.
HOW FARMS CONTAMINATE?
burns fossil fuels that release harmful chemicals such as pesticides or fertilizers into the environment.
HOW IS THE OZONE COMPOSED?
BY 3 ATOMS OF OXYGEN
DETERMINE WHAT IS A WETLAND
AN AREA OF LAND THAT IS SATURATED, OR SOAKED, WITH WATER FOR AT THE LAST PART OF THE YEAR.
Can organisms in deep oceans make photosynthesis? Yes or No, and Why?
No, because sunlight doesn’t reach the deep ocean. So, darkness doesn’t allow photosynthesis.
WHAT DOES THE LAW OF CONSERVATION OF ENERGY STATE?
Energy can’t be created or destroyed, it just changes its form.
Mention the two main ways in which humans impact oceans.
-fishing,overfishing
-coastal development
What is a natural resource AND how are they divided?
A NATURAL RESOURCE IS any natural material that is used by humans.
2 categories: RENEWABLE AND NON-RENEWABLE
EXPLAIN what adaptation plants have in order to survive in an estuary.
Plants have special structures in their roots and leaves that let them get rid of the excess salt.
WHAT IS THE NITROGEN CYCLE AND WHY ORGANISMS NEED IT?
NITROGEN CYCLE IS THE movement of water between the oceans, atmosphere, land, and living things.
ORGANISMS NEED IT to build proteins and DNA for new cells.
WHAT IS EUTROPHICATION?
An increase in the amount of nutrients ,such as nitrates in an aquatic ecosystem is eutrophication.
Describe how the ozone layer protects life on Earth?
It blocks most ultraviolet radiation before it reaches Earth’s surface.
