Which of these describes one or more living organisms that depend on another organism to survive?
bacteria living in the mouth of a dog
aloe vera plants growing next to a fence
mold living on a rock
pufferfish releasing carbon dioxide into pond water.
Aquatic plants have adaptations that help them live in water. For example, the part of the plant that makes food is located on the TOPS of FLOATING plant leaves.
This adaptation helps the plants---
stay anchored
avoid predators
absorb sunight
capture fish
Which observation describes how a lizard interacts with a living element in its environment?
The lizard basked on one of the rocks.
The lizard ate a cricket off of a leaf.
The lizard drank water.
The lizard scattered sand with its tail.
The container for a worm farm needs to have a lid, but the lid must be left partially open because worms require which of the following in order to survive?
sunlight
carbon dioxide
oxygen
helium
All of the following observations are ways that a bird interacts with nonliving parts of its environment EXCEPT---
reacting to morning sunlight by singing
drinking and taking a bath in a puddle of water
responding to cold temperatures by fluffing its feathers
feeding insects to its chicks
Tropical climates have warm temperatures and abundant sunlight all year. What must be available for plants in these climates to make their own food throughout the year?
water
bacteria
shade
birds
Which suggestion involves interactions between two groups of living organisms?
Reduce soil erosion by keeping livestock away from the banks of the pond.
Allow plants to grow along the shoreline to provide cover, nests, and food for wildlife.
Float logs near the edge of the water to provide habitats for salamanders.
Add large rocks to provide sunning for turtles.
Which organism obtains energy without depending on another organism?
oak tree
mushroom
cottontail rabbit
mountain lion
Which of these living organisms was interacting with another living organism in the environment?
A fire ant digging a tunnel in sandy soil.
A blue jay drinking water from a puddle.
A bee collecting pollen from a tree.
A hawk circling in the air over a tree.
The roots of the prickly pear cactus spread out in a wide underground network. How does this type of root system BENEFIT a prickly pear cactus?
By producing fruit and storing water.
By capturing sunlight and getting rid of waste materials.
By absorbing water and supporting the plants in loose, sandy soil.
By releasing nutrients into the sandy soil and taking in oxygen.
Which of these facts best describes how cattle egrets depend on other animals to survive?
They have yellow bills and light orange legs.
They make nests in trees away from predators.
They eat ticks off cattle while the cattle graze.
They are often found in the same fields as cattle.
Some beetles break down the remains of dead animals. Some mushrooms break down the remains of dead trees. How do these actions most BENEFIT plants?
By returning nutrients to the soil.
By releasing oxygen into the air.
By making space for new animals.
By decreasing the population of herbivores.
Which fact best describes one way this bird changes its environment to meet its needs?
Builds nests on hillsides covered with dense vegetation
Usually raises one group of young each year
Hunts for insects and spiders on plant leaves
Feeds on sugar water and peanut butter at feeders
In fall and winter many trees lose their leaves in response to cooler temperatures and ---
decrease in average wind speed
fewer hours of daylight
an increase in humidity
more direct sunlight
