Food chains/webs
What creates all energy for organisms on earth
The sun
Berry bush - rabbit - snake - monitor lizard - hawk
In the food chain above if a disease was to kill most of the snake population what would happen
The rabbit population would grow while monitor lizard population would shrink due to no snake and so would the hawk population
What do you call a substance that can burn easily
Flammable
Gas has a definite volume true or false
false
If there is a drought happening and no rain is going to fal for a long time what will happen to the ecosystems that depend on a river
The River will dry up and the ecosystem depending on it will have no water for plants or animals causing much death and mass migration for those who survive
What do you call the carnivore that has no natural predators
The apex predator
In an ecosystem if all the plants die what would happen in order and detail of events
The primary consumer would have no food and eventually die out or migrate for more food the secondary consumer would then have no food and have the same choice and so would all the other organisms causing mass migration which would put pressure on a different ecosystem to support the organisms that survived and migrated causing more and more mass migration in search off food pressuring more and more ecosystems
The ability of a substance to carry heat or Electricity
Conductivity
Which state has particles tightly packed in a vibrating but fixed position
Solid
If humans over fish a fish species that eats algae what will happen to that fish's ecosystem
The water will be covered by algae taking much of the oxyge and blocking sunlight causing both fish and underwater plants to die
what are the different levels of a food chain
Producer, Primary consumer, Secondary consumer, Tertiary consumer, Apex predator
What do you call the relationship between 2 organisms that get something from each other and support each other
An interdependent relationship
Is sugar soluble
yes
what substance can move through all through states
water
What would happen if humans hunted the an animal to extinction
Any creature that fed on that fed on that animal will also suffer major loss to population and the animals or plants that the animal fed on will have a boost in population
What kind of organism produces its own food
Producers (plants -50%)
What would happen in an ecosystem if all the consumers died to an interspecies disease
The amount of plants would grow
is sand soluble
no
Which process changes a solid object into a liquid object
melting
Are pesticides useful to the environment
No because although they save crops they may be washed into rivers or streams in rain causing harm to other organisms
What kind of plants are not producers
Carnivrous plants
What happens to an ecosystem if the apex predator went exinct
The tertiary consumer would become the new apex predator and its population would grow
Iron rusts under what?
Oxygen and moisture
what process turns a solid into a gas
sublimation
Is destroying habitats for urban growth for the greater good or is it bad
No Demonte its most definitely bad
