• Animal Relationships:

• Symbiosis- a relationship between two different kinds of animals that lasts over time

• Commensalism : a symbiotic relationship where one animal benefits & the other is unaffected

• Parasitism : a symbiotic relationship where one animal benefits & the other is harmed

• Mutualism: a symbiotic relationship where both animals benefit

• COMMENSALISM:

• Hyena/vulture & lion: lion kills his meal, this leaves food for scavengers

Hyena/vulture Benefits: gets food lion Not affected BACK

5.

• MUTUALISM:

• Non-toxic acacia trees & ants most acacia trees have toxic thorns. Some that do not, have ant defenders! The ants are nourished by sugar-water produced by the tree just for the ant & the ant viciously attacks anything trying to feed from its host plant!

Acacia tree Benefits: no herbivores ants Benefits: no herbivores BACK

6.

• PARASITISM:

• Cowbird & other grassland birds brown-headed cowbird is a notorious brood parasite. It will lay its eggs in another birds nest so that the other bird will hatch & raise its chicks.

cowbird Benefits: its eggs get hatched & raised Other bird Hurts: its eggs get ruined BACK

• Grassy, windy, partly dry, sea of grass

• Between dry, arid land and warm, humid land (Usually separates deserts from forests)

• Deep-rooted grasses, few trees and shrubs

• TWO TYPES:

• Tropical grasslands : hot all year with a wet and dry season (savannas) closer to equator

• Temperate grasslands : hot summers, cold winters, higher than equator

8. Tropical grassland: (savannah) Africa 3 Surviving savanna predators 2Survival in the savanna 4 Survival in the S: shelter Surviving Mosquitos

9. Temperate grassland: (prairies, pampas) North America

10.

• Grasslands may also be divided into these two groups:

• Steppes: short grasses, more dry, hot summer, cold winters (Great Plains of US), dust storms (Dust Bowl from overgrazing, plowing, wind)

• Savannah: tropical grasland, dry season & wet (monsoon) season, less season change, shrubs & small trees, grasses (Australia, India, S. America, Africa) --watering holes

11.

• Plants : grasses, sm. trees & shrubs, palms, acacias, boab tree

• Animals :

• hyenas, antelope, zebra, gazelle, lion, rodent, bird, reptile, cheetah

12. Savanna Plants Boab tree Acacia tree Palms

13. Savanna Animals:

14.

• Prairies: tall grasses, more humid,

• hot summers(100degrees F)

• cold winters (-40degrees F)

• (US midwest- fields of corn, wheat,

• sea of grass

• veld -S.Africa

• pampas - Argentina

• Plants : grasses, flowers

• Animals : coyote, fox, skunk, badger, hawk,

• snake, grasshoppers, insects, field birds,

• prairie chicken, prairie dog, bison

16. Prairie Animals:

17.

• Animal Adaptations:

• Animals have adapted to dry, windy conditions

• Grazing animals (eat grass)

• Browser animals (eat leaves & twigs)

• Burrowing animals

• Predators

• Insects

• Savannahs: watering holes
