Living Things
PhotosynthesisEcosystem Structure
Who’s eating who?
Population
Name three characteristics that all living things share?
Living things are made of cells
Living things obtain and use energy
Living things grow and develop
Living things reproduce
Living things respond to their environment
Living things adapt to their environment
What is an organism?
A complete living thing
Which of the following do all living things need to survive?
A – WaterB – OxygenC – Sunlight
D – Carbon Dioxide
A - Water
What is happening in this experiment?
Oxygen bubble are being created because of photosynthesis.
Name a producer, primary consumer, secondary consumer
and tertiary consumer.
I’ll accept any reasonable food chain!
What part of a plant does photosythesis take place in?
The leaves (and sometimes stem)
Name two things plants need for photosynthesis.
CO2 and H2O
What is the green color that helps with photosynthesis?
Chlorophyl. The green pigment found in chloroplasts in the paliside/mesophyl leaf layer
What are two products of photosynthesis?
Glucose and Oxygen (and water)
What is the source of energy for all producers?
The Sun. (which is used by plants in the process of
photosynthesis)
What is a population?
A group of organisms of the same kind living together in the
same area
What is a community?
All of the populations living in the same place
Name 3 biotic and abiotic factors of the Scofield campus.
I hope you named three living things and three of the following abiotic
factors (water, soil, rocks, air, temperature, humidity etc.)
What is an ecosystem?
All of the living and non-living things in a given area that interact
with one another.
Name 3 CT ecosystems
Could be: forest, pond, meadow, salt-marsh, grassland, lake, long
island sound etc.
What is a producer?
An organism that makes its own food (plants)
Are humans herbivores. carnivores, or omnivores and
why?
Omnivores: because we eat plants and animals
What are decomposers and why are they important to an
ecosystem?
Bacteria and fungus that break dead organisms down to recycle
their nutrients into the ecosystem.
Name a secondary consumer in this food web.
mouse, spider or rat
Extra credit: What do the arrows in the food web mean?
What is this and what is it showing me?
Energy pyramidIt shows the loss of energy
between trophic levels10% moves up each level!
Give me an example or a predator / prey relationship?
Any reasonable answer accepted!
What are immigration and emigration?
Immigration is moving into a population.
Emigration is moving out of a population.
What is population density?
The number of individuals or organisms in a certain area
Name 4 limiting factors?
1) Climate2) food and water availability3) Physical space4) Disease5) Predators
In this graph, where is the carrying capacity?
I hope you said…the dotted line!
