Movie 1
The universe has existed for how long?
13.8 billion years
How long can a cheetah go without food?
A week
How long ago was our sun created?
4.6 billion years ago
What organisms perform photosynthesis?
Producers
What organisms can do cellular respiration?
All
What climate and environment conditions make it hard for predators to hunt in Tanzania?
Dry, desolate plains
What does chlorophyll in the chloroplasts do for the plant?
Absorb sunlight
Animal cells have an organelle that harnesses energy. What is this organelle called?
Mitochondria
What organelle is needed to perform photosynthesis?
Chloroplasts
The mitochondria produces what type of energy?
ATP
What process powers our sun and all the stars in the universe?
Nuclear Fusion
Why do wildebeests have four stomachs
To break down grass and other plants
Why do wildebeests travel hundreds of kilometers each year?
To find and search for food
What are the reactants (energy and matter) needed for photosynthesis?
Carbon dioxide, water, and sunlight
What are the two reactants of cellular respiration
ESM (Glucose/sugar) and oxygen
What type of lives do animals live in Serengeti?
Competition (fierce battles for food)
Only 5 percent of cheetah cubs make it into adulthood, what is the cause of this?
Starvation and predators
Energy is broken down and transformed to power and sustain life but where does it all begin?
Sun
If sunlight increased, what happens to the amount of carbon dioxide in the air?
Decreases and is use to make ESMs
What happens to the carbon dioxide when all the decomposers die?
Decreased
How much energy is blasted out from the sun and what type of matter is it?
4 and a half trillion atomic bombs; Plasma
Photons can take up to a million years to escape the sun’s core. Why is that?
They get reabsorbed, released, and redirected by the atoms in the sun until it escapes to the surface
Stars go through different stages throughout their life. Briefly explain how our sun will turn into a white dwarf.
Our sun will expand into a red giant, then continue to expand until it becomes white dwarf.
What is the balanced equation for photosynthesis?
6CO2 + 6H2O ---> 6O2 + C6H12O6
What happens in one part of the ecosystems when carbon decreases in the other?
It will increase since matter cannot be destroyed.
