Marine ecology

What is marine ecology studying?

• matter, its fundamental components, its movement and behavior in space and time

• lands, features, inhabitants and phenomena of the Earth and planets

• marine-life habitats, populations, and interactions among organisms and the surrounding environment

• the atmosphere (which includes atmospheric chemistry and atmospheric physics), which focuses on weather forecasting.

What does the study of marine ecology include?

• influence of geology, geography, meteorology, pedology, chemistry, and physics on marine environments

• compounds consisting of atoms, molecules and ions: their composition, structure, properties of substances

• numbers (arithmetic and number theory), formulas and related structures (algebra), shapes and spaces

• all aspects of life, in particular: structure, functioning, growth, origin

What happens when chemical nutrients are throwing into the ocean’s ecosystem?

• penguins will disappear :(

• the number of the earth's population is decreasing

• the temperature rises with a layer of lithospheric plates

• leads to reductions in oxygen levels, the decay of plant life, and a severe decline in the quality of the seawater itself

The phenomenon of thermal pollution . What are the consequences?

• the ability of organisms to absorb protein decreases

• animals and plants that cannot survive and die out

• the number of reef corals is decreasing, pathogens are spreading

• significant growth of new animal species

The water is covered with a layer that does not pass oxygen when...

• algae produce too much of a special type of substances

• there is a release of toxic gases

• there is an oil spill

The main and most difficult-to-decompose type of littering, which marine life is often confused with food

• plastic

• banana skins

• surfactants

• glass

Significantly reduces the concentration of oxygen in the seas:

• debris in the ocean does not decompose and remain in the ocean for years

• huge density of living organisms in water

• the disappearance of brown algae

What is the danger for humans of getting chemical poisons into the food of marine animals?

• development of medicine

• starvation of fish, and as a result, a decrease in profits

• fewer oceanic minerals

• can lead to cancer, birth defects or long term health problems

What is the approximate age of the world ocean?

• 3 billion years

• 30 million years

• 4 billion years

• 6 billion years

If nothing is done now, by 2050 there will be...

• a global heat catastrophe

• more plastic in the ocean than fish

• nothing bad, the amount of pollution will not change

• penguins disappearing :(
