There isn't an actual reason why they are, but they are small because they could have more in one area which could help form anywhere between getting rid of waste and trying to fight an invader, like bacteria.

Answer:

The correct answer is -

1.1 A. herbivore - greenfly

b. producer - rose

1.2. 1 kJ/m2/year

1.3 rose plants will increase, ladybirds will decrease, blackbirds will decrease.

Explanation:

In this food chain,

Rose >>Greenfly >>Ladybird >>Blackbird

Rose plants are the producers as they generate their food and energy and does not depend on other organisms where as greenfly are the primary consumer or herbivore as they depend on the rose plant for their food and energy only, however, ladybird as secondary consumer and blackbird as tertiary consumer depend on greenfly and ladybird respectively.

If rose plants have 1000 kJ/m2 /year of energy and as it is known that only 10% moves to the next tropic level then blackbird would have:

rose = 1000

greenfly = 1000*10/100= 100 kJ

ladybird = 100*10/100 = 10kJ

blackbird = 10*10/100 = 1 kJ

If greenfly removes from here the rose plant will increase as these depends and eat rose plants and lady bird will decrease as these are the primary source of food for lady bird and if ladybird decrease blackbird also decrease.

The atomic number of argon is 18 and its mass number is 40. Describe the number and type of particles
Paul [167]

Answer:

Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.

Explanation:

Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.

The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.

The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.

There are 8 valence electrons in its outer shell, thus:

  • Ar is not very reactive, as it does not require electron sharing in atomic bonding.
  • It shows low conductivity, as there are no free electrons
