6. 
These deer’s feed at night, they eat fruits, cogon grass
and young leaves and buds found near the forest floor.
They also lick on the ashes from burned forest
clearings, it is said that Rusa’s do this because they
receive minerals from the ashes.

8.  Deer live in a variety of different biomes, from tundras
and tropical rainforests. Some deer live in transitional
areas between forests and thickets (for cover) and
prairie and savanna (open space). The majority of deer
live in temperate mixed deciduous forest, mountain
mixed coniferous forest, tropical seasonal/dry forest,
and savanna habitats around the world.

9.  Since deer are herbivores they only eat plants and so its
main competition is with other grass eaters for food.

10.  There are four species of Rusa’s:
 Rusa alfredi
 Rusa marianna
 Rusa timorensis
 Rusa unicolor

11.  Domain: Eukarya
 Kingdom: Animalia
 Phylum: Chordata
 Subphylum: Vertebrata
 Class: Mammalia
 Order: Artiodactyla
 Family: Cervidae
 Subfamily: Cervinae

12.  Early animalia is the Flagellated Eukaryote.
 Early chordata is the Kimberella.
 Early vertebrata is a Myllokunmingia.
 Earliest origin of mammalia is the Sinconodon.
 There is not an earliest origin for artiodactyla but it is
split inot three groups and deer is in the Ruminantia
group.

13.  The earliest fossil deer date to the Oligocene of
Europe. Later on some species were found larger, with
more impressive antlers. They rapidly spread to other
continents. Some extinct deer had huge antlers, larger
than those of any living species. Examples
Eucladoceros and Megaloceros.
 Syndoyocera, Dicrocerus elegans, Archaeomeryx are
three of the first animals that are considered to be
related to the deer.

14.  Their coat can act like a camouflage in the woods
 They can run fast
 Their sense of smell also protects them from harm
 They have long necks that help them see predators
from a distance
 Their eyes help them see in the dark
 They can hear predators approaching

15.  Primary and Secondary Succession would affect these
organisms by a lot. Deer genus’s are herbivores so they
eat herbs such as grass, weeds and etc,. If there is no
soil these herbs cannot grow and if there is no food
then there is no point of the deer’s being there. When
Secondary Succession happens there is soil but there
are no plants. Because there are no plants there is no
vegetation for the deer.
