biomes
Which biome is characterized by very cold temperatures, permafrost, and little plant growth?
tundra
What is symbiosis?
Symbiosis is a close, long-term relationship between two different species living together. It can be beneficial, harmful, or neutral for the species involved.
What is the nitrogen cycle, and why is it important?
The nitrogen cycle describes how nitrogen moves between the atmosphere, soil, plants, and animals. Nitrogen is a crucial element for building proteins and DNA. It is important because most organisms cannot use nitrogen in its atmospheric form and must rely on bacteria to convert it into usable forms like ammonium or nitrates.
What is the main pigment involved in photosynthesis?
Chlorophyll
what's revahs fave color
maroon/red
What type of plants are typically found in a desert biome, and how are they adapted to the dry conditions?
explain it and i'll see if it's right
In a mutualistic relationship, how do both species benefit?
In a mutualistic relationship, both species benefit from the interaction. For example, bees and flowers have a mutualistic relationship, where bees get nectar from flowers, and in return, they help pollinate the flowers.
How do plants play a role in the carbon cycle?
Plants play a key role in the carbon cycle by absorbing carbon dioxide (CO₂) from the atmosphere during photosynthesis. They use the carbon to produce glucose, which is then consumed by other organisms. This helps reduce the amount of CO₂ in the atmosphere.
Where does photosynthesis primarily take place in plant cells?
Chloroplasts
what's revahs fave flower
carnations
Why do animals in the rainforest have adaptations like bright colors or long limbs?
Animals in the rainforest often have bright colors for camouflage or to attract mates. Long limbs or prehensile tails help them move easily through the dense vegetation. These adaptations help animals survive in a complex environment with many layers and competition for food.
What is an example of a parasitic relationship?
An example of a parasitic relationship is between a tick and a dog. The tick feeds on the dog’s blood, which harms the dog, while the tick benefits by getting food.
What process in the water cycle involves water vapor turning into liquid?
The process is condensation. Water vapor in the atmosphere cools and turns into liquid droplets, forming clouds. This is a key step in the water cycle that eventually leads to precipitation, such as rain or snow.
What gas do plants take in during photosynthesis?
Carbon dioxide

How do the climate and soil type of a tundra biome affect the types of organisms that live there?
The climate of the tundra is cold and dry with long winters, which limits plant growth. The soil is often frozen (permafrost), which prevents deep root growth and keeps many plants from thriving. Only hardy plants like mosses and lichens can grow, and only animals that can survive the extreme cold, like Arctic foxes and caribou, are found there.
What is commensalism, and can you give an example?
Commensalism is a type of symbiotic relationship where one species benefits, and the other is neither helped nor harmed. An example is a barnacle on a whale. The barnacle benefits from being carried to different feeding areas, while the whale is unaffected.
What is the role of bacteria in the nitrogen cycle?
Bacteria play a vital role in the nitrogen cycle by converting nitrogen into forms that plants can use. Nitrogen-fixing bacteria convert atmospheric nitrogen into ammonium, while nitrifying bacteria convert ammonium into nitrates. Denitrifying bacteria return nitrogen to the atmosphere by converting nitrates back into nitrogen gas.
What is the sugar produced during photosynthesis called?
Glucose

What is the main difference between a temperate forest and a tropical rainforest biome?
The main difference is the climate and location. A temperate forest has four distinct seasons with cold winters and warm summers, and it is located in regions with moderate rainfall. It contains deciduous trees (like oak, maple, and birch) that lose their leaves in winter.
A tropical rainforest is found near the equator and has warm temperatures year-round with high rainfall. It has dense vegetation, and the trees are mostly evergreen (they don’t lose their leaves), which allows for high biodiversity and year-round plant growth.
How does mutualism differ from parasitism?
In mutualism, both species benefit from the relationship, while in parasitism, one species benefits at the expense of the other. For example, oxpeckers (birds) eat parasites from the backs of buffalo (mutualism), but a tapeworm harms its host while benefiting from absorbing nutrients (parasitism).
How does water move through the environment in the water cycle?
Water moves through the environment in the water cycle through processes like evaporation (water turning into vapor from bodies of water), transpiration (water released from plants), condensation (vapor forming clouds), and precipitation (rain, snow, etc.). Water then collects in rivers, lakes, and oceans, starting the cycle over again.
What is the main byproduct of photosynthesis?
Oxygen
