The shape of fish is streamlined over time to move faster in water. Which kind of adaptation is this?
behavioral
structural
Which of the following is a mutually beneficial, symbiotic relationship?
Sea sponges and coral compete for food and marine resources. If the sea sponges have sole access to the resources, they will be successful – but the coral will die. A lack of coral negatively affects the reef, which means that sea sponges could die.
Head lice live on small amounts of blood on the scalp. The host human feels itchiness in their hair as the lice bite and move around.
A spider uses a tree to build its web. The tree is not impacted but the spider needs the tree for shelter and safety.
When a fruit bat eats the fruit from a fig tree, it eats the seeds as well. These seeds are dispersed through the bat’s droppings.
The relationship where two different organisms live closely together for long periods of time is called:
predation
competition
symbiosis
What is an example of a third-order consumer's interdependence with a producer?
A human ate a bear, that ate a fox, that consumed a field mouse, which ate a shrub.
A bear ate a fox, that consumed a field mouse, which ate a shrub
A fox consumed a field mouse, which ate a shrub
A filed mouse ate a shrub.
What does the term “biodiversity” mean?
The range of different species in the environment
The effects of physical and non-physical factors on the environment
The daily and seasonal changes in the environment
Sheep and kangaroos both eat the same grass in a paddock. This is an example of-
predation
parasitism
symbiosis
competition
Define autotrophs:
(a)
A lion hunts and eats a deer. What is the role of the lion in the ecosystem?
prey
hunter
predator
parasite
Factors that are least likely to affect populations of organisms on earth are:
number of cyclones and droughts
amount of food and disease
movements of planets and stars in other solar systems
How do animals get nitrogen?
bacteria
lightning
the atmosphere
eating other organisms
How do plants get the nitrogen they need?
from the air
from the soil or water in which they live
from broken-down rocks
What breaks down biotic wastes and dead organisms and returns the raw materials to the ecosystem?
a decomposer
a producer
a consumer
True or False. The nitrogen in the atmosphere is in the right form for living things to use.
true
false
List three ways that cause carbon to be released into the atmosphere as carbon dioxide.
exhaling
burning of fossil fuels
photosynthesis
cellular respiration
How does carbon in a grass plant get into a lion?
The lion absorbs the carbon given off by transpiration
Carbon from grass doesn't end up in a lion.
The lion breathes in carbon given out by the plant
The lion eats an antelope that ate the grass
What is the best definition of animal adaptation?
Changes to an animal's diet.
Characteristics that help animals survive.
Skills learned in order to hunt.
Some animals are able to copy other animals in order to look more dangerous to get away from predators. What is this called?
migration
hibernation
camouflage
mimicry
The black bear’s primary diet is fruit, nuts, honey, and berries. However, they also like to eat fish and small mammals. Their long, sharp claws make it possible to climb trees in order to reach some of their food sources. Black bears also have an extremely good sense of smell. Their long nose allows them to smell up to 20 miles away. This is 100 times better than humans can smell. The black bear’s tongue is sticky allowing them to easily eat ants, berries, and nuts. Black bears also have extremely strong legs, allowing them to move rocks and other obstacles out of their way to get to their food. SELECT ONE EXAMPLE OF THE PHYSICAL ADAPTATIONS LISTED ABOVE.
Eating nuts
Eating fish and small mammals
Sticky Tongue
Moving rocks
I am a grey goose who loves to fly. Every fall when it starts to get cold, I fly south for the warmth. Once my home warms up, I know it is safe to go back home. What adaptation is this?
migration
hibernation
camouflage
mimicry
What does this diagram display?
The predator-prey relationship between vertebrates
The movement of energy throughout an ecosystem
The changing types of organisms in a forest
The standard lifespan of trees and animals
