Section 15, 16, & 17

Ecology, Human Impacts, and Plant Tropisms

QuestionAnswer
Abiotic Factors they are nonliving factors of an environment such as temperature, wind, water, that affect the living factors
Biotic Factors they are living factors of an environment (predators limit populations of prey)
Symbiotic Relationships Predator / Prey, Commensalism, Mutualism, Parasitisms, and Competition
Predator / Prey an eagle preys on rabbits
Commensalism one organisms benefits and the other doesn't but it's not harmed either
Mutualism in this case both organisms benefit
Parasitisms one organism benefits and the other one is harmed
Competition it occurs when overpopulation of organisms creates a demand for resources
Carbon Cycle plants take in CO and turn it into sugar in 2 the process of photosynthesis
Food Chain they show the transfer of energy from one organism to another
Food Web they show all the transfers in an ecosystem
Climate Change humans burn fossil fuels which add extra CO 2 to the atmosphere & natural processes such as volcanoes can produce excess CO 2 which can also lead to climate change.
Habitat Destruction they care caused by deforestation or acid rain can lead to the endagerment of species
Phototropism they are cells on the side of the plant opposing sun elongates so that the leaves turn toward the sun
Geotropism (Gravitropism) is when seeds germinate the roots always grow down and the stem up regardless of how the seed is oriented
Thigmotropism plants exposed to lots of wind grow shorter and stouter than those that are not, also some plants curl up when touched or at dark

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
