the largest sea turtle species
leatherback sea turtle
one living thing is also known as a(n)
individual organism
the ultimate source of energy in a food chain or food web
the Sun
symbiotic relationships occur between two or more organisms of (different/the same) species
different
Over the last century or so, scientists have recorded that the Earth's temperature has (increased/decreased/stayed the same).
increased
the shell of a sea turtle is also called its
carapace
the nonliving factors in an ecosystem are also known as
abiotic factors
Which tropic level has the greatest amount of energy?
producers
the symbiotic relationship where both organisms benefit is also known as
mutualism
What atmospheric gas largely contributes to global climate change?
carbon dioxide (CO2)
the only sea turtle species that is an herbivore as an adult
green sea turtle
all of the biotic factors inhabiting the same area are known as a(n)
community
In the food web, the collared lizard is considered a
secondary consumer
Identify the 2 organisms that are involved in a parasitic relationship.
parasite and host
Name the event that occurs in coral reefs that is a direct effect of climate change.
coral bleaching
the scales on a sea turtle's shell are called
scutes
sand, water, temperature, sunlight, rocks
In the food web, Gila woodpeckers are considered
secondary and primary consumers
What type of symbiosis is represented in this example:
Crocodiles get meat stuck in their teeth and are unable to clean it out themselves. This food can rot their teeth. Fortunately, a bird called the Egyptian plover will be permitted by the crocodile to pick out the food stuck in its teeth.
mutualism
Climate change produces rising sea levels and higher ocean temperatures. How do these affect sea turtle populations?
1. Rising sea levels can flood sea turtle nests
2. Increasing water and sand temperatures mean skewed ratios of female sea turtles
the sea turtle species that is NOT found in Australia
Kemp's ridley sea turtle
List all of the levels of ecology in order from largest to smallest.
biosphere, ecosystem (biome), community, population, individual
If the producers in an ecosystem have 9,000 kcal available to them, how much energy will the tertiary consumers receive?
9 kcal
What type of symbiosis is represented in this example:
In the rainforest, small plants called bromeliads live on the branches of tall trees which allows them to be above the shade on the forest floor to get sunlight for photosynthesis. The tree is not hurt by the bromeliads.
commensalism
List four of the five threats to biodiversity that can affect an ecosystem. (Hint: "HIPPO")
H - Habitat loss
I - Invasive species
P - Pollution
P - Population change (of humans)
O - Overharvesting
