Last Science Qui

Over time, species develop ____ to help them survive in their environment. These are called, ________, traits that makes a population better able to live and reproduce in its environment.

traits; Adaptations

Charles Darwin was a __________ (studied nature) who lived in the 1800s

naturalist

What questions did Charles Darwin ask?

Did species change over time?

How did living things inherit the traits that made them able to survive in their environment?

What did Charles Darwin realize?

Changes in species happen over long periods of time (sometimes thousands of years!)

These changes are the result of many small changes in DNA (mutations) that build up in a population over long periods of time

All living things are struggling to survive because there are not enough resources (like food and shelter) for all of them to survive and reproduce

These finches all came from the same ___________ (the middle). Small changes over time resulted in them becoming different ________.

common ancestor; species

What is the definition of Natural Selection?

Organisms in a population with certain traits are more likely to survive and reproduce than organisms with less favorable traits for that environment

Longer beaked birds are able to ______ and _________ in area where worms hide with tree holes better than birds with short beaks. Long beaks can reach their _____ better, therefore survive and reproduce offspring with long _____.

survive; reproduce; food; beaks

As a result, traits in a ________ change overtime!

population

During the Industrial Revolution, the _______ coated the trees with ______, changing trees to a black color.

pollution; soot

After this, the traits that help ______ and reproduction in the changed environment become more common. The black peppered moths were better able to survive and ________ in this changed environments. However, not all species are equipped to _________ these drastic and sudden changes!

survival; reproduce; survive

The human population has been growing faster and faster since there are __________________.

very few limiting factors

Human have continued to ________________ that slows the growth of most other species as we develop new technologies to help support our ever-growing population.

work around carrying capacity

Humans rely heavily on ________ to provide us with our own resources such as food, medicine, and water purification.

biodiversity

How do Humans negatively impact biodiversity around the world?

Through land-use change, pollution, invasive Species, and Resource exploitation.

What is land-use change?

When humans may destroy natural landscapes  in order to gather resources or build homes. This reduces available habitats and food sources for organisms.

How can Pollution occur?

It can occur from the  disposal of chemicals or from energy sources (noise and light pollution).

Invasive Species, brought to an ecosystem unintentionally or intentionally by humans, may __________ native organisms and _________ them.

outcompete; displace

What is Resource Exploitation?

It’s when humans consume large amounts of resources for their own needs.

Recycling products made from __________ resources can ________ resource exploitation.

nonrenewable; reduce

Conservation efforts work to ________ species and the places in which they ______.

protect; live

Protect biodiversity hotspots, which are a __________ for protecting.

high priority

Captive-breeding programs may help protect endangered ________ by maintaining a _______ population of endangered species in captivity.

species; healthy

Development and use of renewable resources, like ______ or ______ energy, can help decrease resource exploitation

solar; wind
