A student walks the schoolyard and observes that there are many organisms such as different plants and animals.
She notices that moss grows in moist, shady areas but did not see any in the open yard where it's sunny.
What is the best explanation for her observation?
Schoolyards are the only places where moss can grow.
Different habitats support different plants and animals.
Schoolyards are not able to sustain living things.
Which animal and plants would naturally live in the pictured biome?
Deciduous trees and potbelly pigs

Cacti and snakes
Students make plans to construct an ecosystem in a large aquarium. All 4 plans include soil and water. Which ecosystem will MOST LIKELY be sustainable?
WHY?
A-fish maintain water quality in the ecosystem
C-ecosystems with fewer species are more sustainable
D- ecosystems with more species are more sustainable
An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms leaving the ecosystem or dying.
Increased biodiversity results in a more sustainable ecosystem because-
a greater number of plant species means there is less barren land
a greater variety of species present allows more organisms to adapt after the natural disaster

800
0
200

Autotrophs
Organisms that can make their own food from their environment.
Heterotrophs
Organisms that cannot make their own food
Prokaryotic
Cells that do not have a nucleus or organelles
Eukaryotic
Cells that have a nuclei and organelles

There are approximately 113 species and subspecies of snakes in Texas. Why would it be important for scientists to use a standardized taxonomic system when naming each species of snake?
To ensure that ll species of snakes are located in the fossil record.
To avoid confusion in the identification of a variety of snake species
To determine the impact of removing one species of snake from their habitt in the ecosystem.
Having a standard taxonomic system benenefits the scientific community by allowing scientists from all over the world to do which of the following?
Have a common system for the classificationof locations containing fossils.
Use similar system to classify the impact of removing species from ecosystms.
Have a common understanding in the classification of organisms.
Fox squirrels are common in Texas. Fox squirrels primarily eat acorns and nuts from trees but also eat insects. Some predators of fox squirrels include owls, snakes, and bobcats.

Raccoon and sparrow
Raccoon and Eastern cottontail rabbit
Sparrow and Eastern cottontail rabbit
Students designed an experiment to model the carbon cycle. The students combined water and carbon dioxide-producing disks in a sealed flask. The flask represented Earth’s atmosphere, and the lamp represented the sun.
Which component can be added to the flask to reduce the concentration of carbon dioxide in the model atmosphere created by the disks?
Bacteria to use carbon during nitrification
Plants to absorb carbon in the process of photosynthesis
Snails to use carbon through respiration
Which statement is an example of how carbon moves through a food chain as part of the carbon cycle?
Producers release carbon dioxide, and consumers take it in.
Producers take in carbon dioxide, and consumers release it.
Producers release carbon into the soil, and consumers take it in from the soil.
A correct path that nitrogen could take would be
air -> animals -> plants -> bacteria
bacteria -> air -> plants -> animals
air -> bacteria -> plants -> animals
