organisms that feed on dead matter
detritivores
loggers often plant trees to replace forests they have cut down. Do you think that planting one tree for every tree cut down will fully replenish the ecosysytem
Where there is rich soil a forest can be revitalized through secondary succession;that we can never be sure whether or not a forest ecosystem will return to its original state;and that a natural forest consists of many species of different ages, while the new trees will be the same age and probably the same species.
if you weighed all living things on Earth 99% of the biomass would be...
producers
the regrowth of trees following a forest fire is secondary succession.
true
Which cell organelle contains the genetic material
the nucleus
animals that have no predators when they are healthy adults
top carnivores
list the trophic levels of the food web in order from lowest to highest.
producers, primary consumers, herbivores, secondary consumers, tertiary consumers
the type of organism most likely to be at the top of an ecosystem's energy pyramid is a...
carnivore
without decomposers, our world would fill up with dead material
true
If a moving object is acted on by no outside forces, what will it do
It will continue moving at the same speed and in the same direction, according to Newton’s first law of motion.
the network of food chains in an ecosystem
food web
explain what a biological clock is, and give two examples of how organisms are affected by their biological clocks.
it is an inner mechanism that regulates an organism's daily and seasonal rhythms. Examples - jet lag, waking and sleeping cycle, migration in birds, hibernation in animals.
a food chain is made up of an oak tree, and insect, a mole and a raccoon. The producer would be the...
oak tree
secondary succession raley takes place in rainforests because they don't get much sunlight
false its because the soil is poor
What is the chemical symbol for gold on the periodic table and the origin language
Au from the Latin word aurum
animals that eat primary carnivores
secondary carnivores
give two examples of circadian rhythms.
sleeping, plants opening and closing, changes in heart rate and body temperature.
the ultimate source of all energy that flows through the food web is...
the sun
interspecies competition is more fierce than intraspecies competition.
false it is the other way around
what are all the different moon phases. (if you get it in order double points)
new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent
organisms that get their energy by breaking down the remains of dead organisms or animal waste
decomposers
explain the transfer of energy from producers to various consumers as it moves through the food chain
0.1 percent of solar energy that falls to the earth is used in photosynthesis by producers. With each trophic level, more energy is lost and less is stored in the biomass of the animal
lichen is an organsim in which fungus and algae live together, The fungus provides water and protection and the algae provides food through photosynthesis. What type of relationship is this.
Mutualism
migration is an example of a circadian rhythm
false it is an example of a biological clock
What is the law of conservation of mass
It states that mass is neither created nor destroyed in a chemical reaction. Therefore, the mass of the products must equal the mass of the reactants.
