#10. Ecological Principles
During succession species that colonize in early seral stages tend to have different life-history characteristics than those that colonize in later seral stages ;
A) Early seral stage in succession
B) Late seral stage in succession
i) Good seed dispersal ability
ii) Lower plant efficiency in low light
iii) Seed dispersal by animal
iv) Slower the resource acquisition
v) Found large biomass
vi) Seed longevity is long type
Which of the following is the correct prediction about early and the late successional seral stage?

#6. System Physiology – Plant
There are the five groups of late embryogenesis abundant (LEA) proteins found in plants
Group
(family name) |
Functional information |
I) Group 1 (D-19 family) |
a) It is an
abundant protein in cotton embryos, Each putative dimer of this group may
bind as many as ten inorganic phosphates and their counterions |
II) Group 2 (D-11 family) |
b) Possibly functions in ion
sequestration to protect cytosolic metabolism When LE25 is expressed in
yeast, it confers salt and freezing tolerance |
III) Group 3 (D-7 family) |
c) In tomato, a
gene encoding a similar protein is expressed in response to nematode feeding |
IV) Group 4 (D-95 family) |
d) Contains more
water of hydration than typical globular proteins Overexpression confers
water deficit tolerance on yeast cells |
V) Group 5 (D-113 family) |
e) Often
localized to the cytoplasm or nucleus More acidic members of the family are
associated with the plasma membrane May act to stabilize macromolecules at
low water potential |

Herbivore ingests plant material with 1000 k j energy form producer and assimilated only 200 k J energy in their blood stream; additionally herbivore invests 120 k j energy in their maintenance. What is production efficiency of that herbivore?
