2024 Semester 1 Final Review-5th per

Photosynthesis and Cellular Respiration

100

Is this equation photosynthesis or cellular respiration? 

6CO₂ + 6H₂0 --> C₆H₁₂O₆ + 6O₂

200

In plants, what helps the plant conserve water when water is limited? 

the stomata

300

What is the chemical formula for glucose? 

C₆H₁₂O₆

400

How are photosynthesis and cellular respiration connected? 

The equations are opposite, what humans need is opposite of what plants need. 

500

How does the flow of carbon work in photosynthesis?

Carbon flows from the atmosphere and is absorbed in plants. It becomes part of glucose and animals ingest it. 

Populations and Relationships

100

What is it called when a population has reached its maximum resource load? 

Carrying capacity

200

What is a niche? 

A unique role a species plays in an ecosystem. 

300

What is the difference between exponential growth and logistical growth in an ecosystem? 

Exponential growth means that a population continues to grow due to no predators or is an invasive species, logistical growth means that a population hits the carrying capacity of an ecosystem.

400

What are the 3 types of symbiosis? 

mutualism, commensalism, parasitism

500

What are 3 different limiting factors? 

natural disaster, predation, competition, food, reproduction, invasive species, immigration, emmigration

Food Webs and Energy

100

What percent of energy is transferred to each part of the trophic pyramid? 

10%

200

What is an animal that doesn't have a predator called? 

apex

300

Which direction does the arrow point in a food chain or food web? 

toward the predator that is receiving the energy

400

Which type of organism has the most biomass on the planet? 

producers

500

Which of the following is the secondary consumer in the food chain:

lily pad --> snail --> frog --> alligator 

frog

Cycling of Matter

100

What type of ecological succession starts with bare rock? 

primary succession

200

How do you determine if an ecosystem has a high level of biodiversity?

count all of the species

300

Where is the most carbon stored on earth? 

fossil fuels

400

What gas is released in the nitrogen cycle during Nitrogen fixing phase? 

Ammonium (NH₄)

500

What are the 2 main processes used during the carbon cycle? 

photosynthesis or cellular respiration

Vocabulary

100

What is a heterotroph? 

consumers who eat other things (omnivore, carnivore, herbivore)

200

What is a pioneer species in primary succession? 

moss or lichen

300

What is an ecosystem? 

Abiotic and biotic things interacting

400

What is symbiosis? 

the ecological relationship between different species in an ecosystem

500

What does biogeochemical cycle mean?

How the earth, molecules and living things exchange energy over and over again on Earth.
